Verdict
The clearest difference is in-app purchases: VECTROX at none against Alien Evolution's 2. VECTROX also leads on ads (none vs shown) and rating (5.0 vs 4.8). Alien Evolution's advantage is ratings volume (19 vs 1). On price, review sentiment, device support and iOS requirement there is nothing between them.

VECTROX holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Alien Evolution has 19 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
