Verdict

The call

The clearest difference is in-app purchases: MDI Connect at none against Explore Hong Kong's 1. MDI Connect also leads on ads (none vs shown) and update cadence (every 6 weeks vs every 5 months). Explore Hong Kong's advantage is device support (3 vs 1) and iOS requirement (14.0 vs 17.0). On price there is nothing between them.
