Just got my Varmilo VA87M with Gateron clears from Massdrop. From a general smoothness perspective, these switches blow stock Cherry MX red and black out of the water. I am having trouble coping with how light they are. I ordered mine with white backlighting and it looks really nice against the standard caps. Speaking of the caps, these are some of the best stock ones I've ever used. I'd love to compare them to the ones on the Leopold FC750R, but I will say they're easily as good as those found on a Realforce or HHKB.
I plan to keep this board as backup to my BlackWidow at home, as I think these switches will work well for gaming. I don't think I'd recommend Gateron clears for typists unless you have an extremely light touch.
