Verdict
The clearest difference is price: Alien Tower at Free against Rainbow Monsters's $0.99. Alien Tower also leads on device support (3 vs 1) and iOS requirement (15.0 vs 17.6). Rainbow Monsters's advantage is ads (none vs shown) and update cadence (every 2 months vs every 5 months). On in-app purchases there is nothing between them.
