Verdict

The call

Two Factor Authenticator & OTP and eSign both sit at 4.5 stars, but that hides the real split: 100% of Two Factor Authenticator & OTP's written reviews are positive against 33% of eSign's. Two Factor Authenticator & OTP also leads on update cadence (every 2 days vs every 2 weeks) and iOS requirement (15.1 vs 18.6). eSign's advantage is monetization model (free with in-app purchases vs subscription). On price, rating, ratings volume and ads there is nothing between them.
