IMHO, it's the weight rather than the height. I like using them on 62g ErgoClears.
I game on all Row 3 and fully sculptured SA and find it's just fine on 62g ErgoClears and Browns, no real difference in terms of responsiveness, etc than the Cherry or OEM caps I use. The keys do feel different, but it affects typing more than gaming. Oh, and fingers love the spherical keytop feels.... mmm, good.
