Zest Codes is a newer YouTube channel that has gained traction with bite-sized CompTIA exam tips, acronym summaries, and quick-review content. Messer is the established full-course option. In 2026, here's how to use both effectively rather than choosing between them.
Messer wins on objective coverage and update cadence — his free playlists are organized to the published exam objectives. Zest Codes wins on shorter, exam-tip-focused content and quick acronym recaps. For most candidates, Messer is the primary source and Zest Codes is a complement for last-week review, not a replacement.
Different Roles, Not Direct Competitors
Messer publishes full objective-by-objective courses. Zest Codes specializes in shorter, high-impact recap videos — acronym roundups, last-minute exam tips, and topic-specific quick hits.
Treating them as alternatives misses the point. They work best as primary content (Messer) plus rapid review (Zest Codes), especially in the final week before exam day.
Where Messer Is Stronger
- Full course coverage. Messer's playlists map every published exam objective. - Track record. Years of pass-rate validation across thousands of candidates. - Update timing. Messer refreshes when CompTIA changes objectives. - Depth. Concepts are taught from first principles, not summarized.
Where Zest Codes Helps
- Acronym packs. Quick visual roundups of acronyms candidates routinely confuse. - Exam-day mindset videos. Short tips on pacing, PBQ strategy, and flagging questions. - Topic refreshers. Useful as a "second voice" when a Messer explanation isn't clicking. - Last-week review. Compressed content is ideal when you're past the learning phase and just need reinforcement.
The Recommended Combination
Weeks 1–6: Messer full course + free practice questions. Weeks 7–8: Add Zest Codes recap videos for review, plus timed full-length practice exams. Final 3 days: Zest Codes acronym videos and exam-day strategy content only.
This sequencing uses each channel where it's strongest and avoids wasting time on overlap.
The Creator Comparison That Matters
Messer is a near-two-decade veteran with deep instructional design experience and a steady update cadence aligned to every CompTIA objective refresh. Zest Codes is newer to the CompTIA space and focuses on shorter-form supplemental content — acronym drills, exam-day strategy clips, last-minute recap videos. They serve different study moments. Treating them as direct alternatives misses the point: Messer is the foundation, Zest Codes is a supplement for the final two weeks of prep.
When Zest Codes Content Actually Helps
Zest Codes' acronym videos are useful for cramming the last 50-100 abbreviations that always show up on CompTIA exams (XDR, SOAR, EDR, MDR, CSRF, XSS, and the rest). His exam-day strategy clips are also useful for first-time CompTIA candidates anxious about the test interface. For primary content delivery? Stay with Messer. For final-week supplemental review? Zest Codes earns 1–2 hours of your time in the home stretch.
Production and Pacing Differences
Messer's videos are clean, instructional, and tightly edited — they feel like a structured course. Zest Codes leans into a faster, more energetic delivery designed for mobile-first watching during commutes or short breaks. Neither is universally better. If you study primarily at your desk in focused blocks, Messer's style works. If you study in 10-minute chunks on your phone between meetings, Zest Codes' format may fit your schedule better. Both are free, so try both and use what your schedule actually allows.
Cost and Availability
Both creators publish primarily on YouTube at no cost. Neither requires subscriptions for core content. Messer sells optional $25 practice exams; Zest Codes occasionally promotes a paid course or merch but the bulk of his teaching is free. Total cost to use both: $0–25. There's no reason to choose one over the other on cost grounds — use both as the calendar and your learning style dictate.
Audience Overlap and Where Each Wins
Messer's audience skews toward methodical, objective-by-objective learners who want comprehensive coverage in standardized lesson lengths. Zest Codes attracts visual learners and candidates who respond to higher-energy delivery, motivational framing, and pass-story content. Both audiences overlap heavily on r/CompTIA, where it's common to see candidates credit both creators in the same pass post. If you've previewed both and prefer one's delivery, trust that instinct — neither is objectively better, and switching mid-prep wastes momentum. Pick the voice you'll actually sit through and stick with it as your primary, using the other for second-opinion spot-checks on stubborn topics.
A Combined Free Study Stack
Use Messer as your structured primary: complete his playlist for your cert in objective order, take notes from his free PDFs. Drop in Zest Codes whenever a topic isn't clicking from Messer alone — his alternate explanation often unlocks the concept. Add free CompTIA PBQ samples and r/CompTIA for weak-area questions. Optional paid additions: $15-20 Dion practice pack on Udemy for exam-day calibration, plus Messer's $25 practice bundle as a final-week checkpoint. Total cash spend: $0-45 for a complete, high-pass-rate study system. Most candidates over-spend by buying additional courses that add minimal value over this baseline.
Pro Tips
Don't use Zest Codes as your primary content source — it's built for review, not first-time learning.
Save Zest Codes acronym videos for the final week when you need reinforcement, not deep teaching.
Treat the two channels as complementary, not competitive — they're solving different problems.
Use Zest Codes' exam-day strategy videos in the 24 hours before your exam for mindset prep.
If a Messer explanation doesn't click, search Zest Codes for the same topic for a different angle.
Common Mistakes to Avoid
Using only Zest Codes and skipping a full course — leaves major objective gaps.
Watching every Zest Codes video early in the study cycle when full teaching is what you need.
Treating compressed acronym videos as a substitute for understanding the underlying concept.
Ignoring Zest Codes entirely — the review content genuinely helps in the final week.
Subscribing to paid review services when free YouTube channels cover the same ground.
The candidates who pass on the first try treat full-course channels and review-focused channels as a team. Messer teaches the material; Zest Codes-style channels lock it in during the final stretch.
