The clearest difference is rating: Jupiter Attack at 4.5 against Fish in a Watch's 3.5. Jupiter Attack also leads on monetization model (free vs paid) and ratings volume (389 vs 25).

Jupiter Attack holds the better App Store score, 4.5 against 3.5. That said, the two scores are not equally well evidenced: Jupiter Attack has 389 ratings behind it against 25, so its average is the more settled of the two. Written reviews complicate that: 50% of Fish in a Watch's written reviews are positive against 40% of Jupiter Attack's, so the app with the better star average is not the one people write more warmly about.
