Verdict
The clearest difference is in-app purchases: Silence Meter at none against Lockdown's 3. Silence Meter also leads on update cadence (every 2 weeks vs monthly) and iOS requirement (15.8.3 vs 17.6). Lockdown's advantage is ads (none vs shown). On price and device support there is nothing between them.
