Verdict
The clearest difference is in-app purchases: OTG Flash Pro at none against U8's 1. OTG Flash Pro also leads on ads (none vs shown) and update cadence (every 10 days vs every 6 weeks). U8's advantage is iOS requirement (12.0 vs 14.0). On price and device support there is nothing between them.
