Verdict
The clearest difference is review sentiment: Sky Invaders at 50% against Alien Shooter's 0%. Sky Invaders also leads on in-app purchases (none vs 12).

Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Alien Shooter sells 12 one-off in-app purchases. Sky Invaders asks for nothing beyond the download.
Alien Shooter holds the better App Store score, 4.7 against 1.0. That said, the two scores are not equally well evidenced: Alien Shooter has 43 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 50% of Sky Invaders's written reviews are positive against 0% of Alien Shooter's, so the app with the better star average is not the one people write more warmly about.
Sky Invaders ships an update every 23 months, Alien Shooter every 2 months. The most recent releases landed on September 14, 2026 and October 24, 2026 respectively.
