Verdict
The clearest difference is rating: Mr Autofire at 4.8 against Senpa.io's 3.9. Mr Autofire also leads on update cadence (weekly vs every 9 months) and ratings volume (28K vs 171). Senpa.io's advantage is in-app purchases (none vs 10) and ads (none vs shown). On price, review sentiment and device support there is nothing between them.
