The glutes, hamstrings are mainly used for constant power OOS climbing, especially in long climbs. Big strong quads are great for OOS sprinting. Strong Pro climbers will tend to have skinny legs. Strong Pro sprinters will have bulkier and more muscular legs overall.
The size of the calves don't really tell if one is good for OOS or spinning. Alberto Contador and Chris Froome are the opposite end of the OOS vs climbing seated spinning technique and both of them have small calves. One thing they have in common is they are both very good climbers in TdF, one of the best.
For spinning high cadence, it doesn't matter which muscle group you favor. All you need to do is spend time training at high cadence.
