Verdict
The clearest difference is in-app purchases: Chess9 at none against Gambits Edge's 5. Chess9 also leads on ads (none vs shown). Gambits Edge's advantage is update cadence (weekly vs every 2 months) and iOS requirement (15.0 vs 17.6). On price and device support there is nothing between them.
