Verdict

The call

The clearest difference is ads: GBDev at none against OhMyBoy's shown. GBDev also leads on update cadence (every 4 days vs every 6 weeks) and monetization model (free vs free with in-app purchases). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. OhMyBoy sells 3 in-app purchases, starting at $2.99 per 7 days and GBDev sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
