Verdict
The clearest difference is in-app purchases: 3demp at none against Arduino BT Controller's 1. 3demp also leads on ads (none vs shown) and iOS requirement (11.0 vs 18.2). Arduino BT Controller's advantage is update cadence (every 8 days vs every 10 months). On price and device support there is nothing between them.
