Verdict
The clearest difference is ads: OTA Programmer at none against Schlagbaum's shown. OTA Programmer also leads on iOS requirement (13.0 vs 15.0). Schlagbaum's advantage is update cadence (every 2 weeks vs every 5 months). On price, in-app purchases and device support there is nothing between them.
