Verdict
The clearest difference is rating: Memory Shard at 5.0 against Universe Invader 2's 4.5. Memory Shard also leads on monetization model (free with in-app purchases vs paid). Universe Invader 2's advantage is ads (none vs shown) and update cadence (every 6 months vs every 14 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.
