Verdict
The clearest difference is in-app purchases: accident at none against Mendaco regression's 1. accident also leads on ads (none vs shown). Mendaco regression's advantage is update cadence (every 2 months vs every 41 months) and iOS requirement (12.0 vs 15.0). On price and device support there is nothing between them.
