Verdict
The clearest difference is in-app purchases: GmSpeedPlus at none against Off's 1. GmSpeedPlus also leads on ads (none vs shown) and rating (5.0 vs 4.6). Off's advantage is update cadence (every 4 months vs every 30 months) and ratings volume (763 vs 2). On price, device support and iOS requirement there is nothing between them.
