AdGuard vs SuperchargePerformance: BEST Chrome Pick? (2026)
AdGuard has deeper filter lists. SuperchargePerformance pairs MV3 blocking with tab suspension and RAM tracking. Which Chrome ad blocker fits your setup?
Key takeaways
- AdGuard wins on filter depth: more lists, more granular control, if blocking coverage is your only goal.
- SuperchargePerformance ships 186K+ DNR rules but bundles them with tab suspension, preloading, and a RAM dashboard.
- Choose based on whether you need a dedicated blocker or a full performance tool with blocking built in.
AdGuard and SuperchargePerformance both block ads, but they’re optimizing for different things. AdGuard wants maximum blocking coverage across every filter list it can get. SuperchargePerformance ships 186,000+ DNR rules from 22 open-source filter sources (compiled March 2026) and wants your browser to be faster and lighter overall — blocking is one part of that, alongside tab suspension, memory management, and preloading. If ad blocking is your only goal, that difference matters.

How Blocking Works in Each Extension
SuperchargePerformance uses declarativeNetRequest (DNR) exclusively. Blocking rules are compiled into a static ruleset that Chrome itself applies before network requests leave the browser. The extension does not intercept requests at runtime — Chrome’s engine handles the blocking at the network level.
AdGuard offers a MV3 version (AdGuard MV3) with declarativeNetRequest-based blocking, as well as a legacy MV2 version with more extensive dynamic rule support. The MV3 version has reduced filter capabilities compared to the MV2 version, which is no longer installable on current Chrome versions since MV2 was disabled in Chrome 138 (mid-2025).
Blocking Levels: Tiered Coverage
SuperchargePerformance offers three blocking levels, all free:
| Level | What is blocked |
|---|---|
| L1 (Standard) | Common ads |
| L2 (Strict) | Ads + analytics trackers |
| L3 (High, default) | Ads + analytics + malware/phishing domains |
When AdGuard Is the Better Choice
Ad blocking is your primary goal and you want maximum filter list coverage. You need fine-grained control over specific lists. You’re not interested in tab suspension or memory management and are willing to run multiple extensions.
When a Single-Extension Stack Makes More Sense
You want ad blocking as part of a broader performance setup — tab suspension, memory savings, preloading — without running three separate extensions to cover the same ground. Or you want visibility into how much RAM your suspended tabs are actually saving.
Bottom Line
AdGuard wins on blocking depth — more filter lists, more coverage, more control. SuperchargePerformance wins on breadth — it handles tab memory and navigation performance in the same install. The question is whether you need a dedicated blocker or a full performance tool with blocking built in. Those are different requirements and they have different answers.
