Verdict
The clearest difference is rating: Bug Ring Siege at 5.0 against Star Marines's 4.6. Star Marines's advantage is ratings volume (8 vs 1) and device support (3 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.
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. Star Marines sells 11 one-off in-app purchases and Bug Ring Siege sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
Bug Ring Siege holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Star Marines has 8 ratings behind it against 1, so its average is the more settled of the two.
