What do you mean? Wine has a different architecture because distributing microsoft binaries is not legal, so technically it's not the same thing, but it still does an amazing job and a lot of apps/games works flawlessly.
And a lot don't. And then you have to spend a lot of time researching why and messing around with config options and maybe even compilers. And the games sometimes stop working after an update.
Conversely, if you run Windows, it's rare that you need to work hard to run a game.
This is definitely not my experience.
Off my 100 games on steam, gog and egs, 2 doesn't work straight out of the box.
- rocksmith 2014 that can work by switching to alsa audio but the audio lag make the experience subpar
- bit trip beat that i know can work by changing something but didn't try
It does an amazing job, but a lot of apps and games do not work flawlessly. Or didn't, last time I tried Wine. Maybe this situation has changed a lot since then, which would be awesome.
Holding software to that standard eliminates most of it. "No, I haven't tried Google Docs yet. They're still adding features and fixing bugs. I'm holding out until it's stable."
Context matters a lot. I'm not holding Wine to unreasonable standards, its a matter of recognizing reality of the situation and that Wine is not such a exact mirror of WSL and as such it will continue to have significant issues.
