Verdict
The clearest difference is in-app purchases: UnitsConv at none against Paint Gallery's 1. UnitsConv also leads on ads (none vs shown). Paint Gallery's advantage is rating (4.7 vs 4.3) and ratings volume (68 vs 3). On price, update cadence, device support and iOS requirement there is nothing between them.
