Verdict

The call

The clearest difference is ads: OverclockeTD at none against Color Defense's shown. OverclockeTD also leads on iOS requirement (12.0 vs 16.0). Color Defense's advantage is ratings volume (1.4K vs 9) and update cadence (fortnightly vs every 2 months). On price, rating, review sentiment and in-app purchases there is nothing between them.

Both are free to download. Color Defense sells 10 one-off in-app purchases and OverclockeTD sells 6 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
