You're right about smaller cut, but there are some major factors like visibility, conversion, etc.

Fair enough, I just dislike Steam as a DRM. I have bought software licensed to platforms that have gone bankrupt before. While it seems unlikely that steam dies anytime soon it is the idea of not owning your purchase that doesn't sit right with me. So i try to buy games on DRM free platforms as much as possible.
