The clearest difference is rating: Otteri at 2.0 against 3 ชั้น's 1.0. Otteri also leads on update cadence (every 3 weeks vs every 8 months). 3 ชั้น's advantage is iOS requirement (13.0 vs 15.5). On price, review sentiment, ratings volume and ads there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Otteri holds the better App Store score, 2.0 against 1.0. Both are backed by a comparable volume of ratings — 1 and 1 respectively.
