I can see why you would think that, but there is a reason that many think the opposite. Wine is obviously less compatible than WSL, but it is also a much more ambitious project. For WSL to work, it "only" has to implement the kernel translation layer and then run the various userspace tools that Linux does (GNU tools, Gnome, etc).

For Wine to implement even enough to run Notepad, Wine needs a reimplementation of huge portions of userspace. Of course, this also means it is a little bit of an Apples to Oranges comparison.
