Verdict
The clearest difference is review sentiment: Climb at 100% against Fast Chess!'s 0%. Climb also leads on rating (5.0 vs 3.5) and in-app purchases (none vs 5). Fast Chess!'s advantage is update cadence (fortnightly vs every 17 months) and device support (3 vs 1). On price there is nothing between them.
