Verdict

The call

The clearest difference is rating: PrimalGPT at 4.9 against Sub5's 3.7. PrimalGPT also leads on review sentiment (74% vs 50%) and update cadence (every 4 days vs fortnightly). Sub5's advantage is ads (none vs shown) and iOS requirement (15.1 vs 18.0). On price, in-app purchases, monetization model and device support there is nothing between them.
