In terms of raw quality and features, all three of these are quite similar, especially if you take into account the upgraded G Pro X and Cloud Alpha S. So at that point, it's down to your own subjective tastes. I already exhaustively covered the sound signatures, fit, and build of each of these models in my individual reviews. The G Pro has cheap stickers on the sides that bother me, and if I had to pick one of the models on sound, I'd personally pick the Alpha S or G Pro over the Cooler Master.
Without those two upgraded models in the picture, the Cooler Master has a big advantage on average price, and I'd never begrudge anyone buying the cheapest of something!
It's hard to go "wrong" with any of these, so you'll just have to trust your own personal tastes as a guide and pick the one that holds the most innate appeal to you!
I used to write more comparisons years ago, but now, unless there's some specifically interesting disparity I want to point out, I try to avoid it and let my reviews stand as the most exhaustive form of my opinion. Sound equipment and sound enjoyment are very subjective. Don't sweat trying to buy the "Best," especially since you've narrowed it down to three models with positive reviews. Now, just pick the one you personally like/that looks like it'll be the most fun for you.
