Verdict
The clearest difference is in-app purchases: Open.Line at none against True Caller's 1. Open.Line also leads on ads (none vs shown) and update cadence (every 3 days vs every 3 weeks). True Caller's advantage is iOS requirement (15.1 vs 18.0). On price and device support there is nothing between them.
