The problem isn't Emacs, since the core program works fine on Windows (as does vim). Many packages for both also work just fine.

But then there's that subset of packages that don't work fine. Some can be fixed with fiddling, but then you lose that Emacs thing of installing a package and be on your way (usually a point in favour of Emacs over vim I might add!). And some just can't be fixed, which leaves me either using a different editor for those needs or just not using those packages by using conditional configs.

However then we run into a little peeve of mine: the reason I want to use a tool like vim or Emacs is to have the same tool working the same way everywhere. I don't want to learn and more importantly maintain two setups. I want to sync my one setup across any machine I use and have it work the same way. I also don't want to have the situation that my editor works one way on system A and another on system B.
