Verdict
The clearest difference is in-app purchases: Grav at none against Subway Hoverboard's 2. Grav also leads on ads (none vs shown). Subway Hoverboard's advantage is update cadence (every 4 months vs every 9 months) and iOS requirement (12.0 vs 15.0). On price and device support there is nothing between them.
