Verdict
The clearest difference is price: Reversi Effect at Free against にゃセロ's $0.99. Reversi Effect also leads on update cadence (every 5 days vs every 3 weeks) and iOS requirement (13.0 vs 15.6). にゃセロ's advantage is in-app purchases (none vs 3) and ads (none vs shown). On device support there is nothing between them.
