Verdict
The clearest difference is price: Critter Coasters at Free against Reefs's $1.00. Critter Coasters also leads on in-app purchases (none vs 6) and ads (none vs shown). Reefs's advantage is update cadence (every 3 months vs every 29 months) and iOS requirement (11.0 vs 17.0). On device support there is nothing between them.
