Verdict
The clearest difference is in-app purchases: KaleidoPaint at none against Sudo+'s 4. KaleidoPaint also leads on ads (none vs shown) and ratings volume (77 vs 1). Sudo+'s advantage is rating (5.0 vs 4.6) and update cadence (weekly vs every 5 months). On price, device support and iOS requirement there is nothing between them.
