Verdict
The clearest difference is monetization model: Auth at free with in-app purchases against Authenticator App's subscription. Auth also leads on ads (none vs shown) and rating (5.0 vs 4.6). Authenticator App's advantage is update cadence (every 5 weeks vs every 38 months) and ratings volume (84 vs 4). On price, review sentiment, in-app purchases and device support there is nothing between them.
