Not OP, but I do. In principle it shouldn't really matter what the size of the binary is, but a large binary relative to peers in the program's category usually reflects complexity and bloat. Powershell feels sluggish and unresponsive to me relative to fish, bash or zsh (the three shells I've used most). I was so put off by the feel of powershell five or so years ago that I haven't used it since then. For that reason though, I will concede it's possible it's better now but I'd be pretty surprised given Microsoft's track record.
