Verdict
The clearest difference is in-app purchases: Oppex at none against Developer Tools's 1. Oppex also leads on update cadence (fortnightly vs every 6 weeks). Developer Tools's advantage is device support (4 vs 2) and iOS requirement (13.0 vs 16.4). On price and ads there is nothing between them.
