Verdict
The clearest difference is in-app purchases: My Authenticator at none against HotKey OTP's 2. My Authenticator also leads on iOS requirement (15.0 vs 17.0). HotKey OTP's advantage is update cadence (every 3 days vs every 6 months) and device support (4 vs 2). On price and ads there is nothing between them.
