It comes down what you actually want to do. My time spent on the iPad was defined by what I couldn't do, and it was extremely frustrating, I ended up not doing it instead of go getting the laptop from across the house.
Windows is not refined nor optimized for tablet use by any measure, but it actually does the job, instead of showing a cute and extremely refined middle finger half the time.
The breaking point for me was the reader apps, where I'd have a file and just no way to read it, short of taking 10 min on a desktop to somewhat convert it to what the iPad can handle (see below). Since they're also in a pissing match with Amazon, the reading experience is just subpar. What's the point of a simple and elegant interface if I'm still babysitting what's going in there and have to constantly think about work-arounds that also end up clunky and broken ?
> Art and note apps
Adobe suite, ClipStudio etc. are all there, in their actual, professional, full-blown version, and not some compromised "on the go" version. Same for One-note, obsidian etc., there's no lack of them on Windows while it was a fresh market on the iPad.
> ebook reader apps
I think iBooks is the only reader you don't get (is there a web version ? I have no idea).
Granted I buy most of my books on kindle, the in-browser reader works well enough (in the end, I'm full screen turning pages, so makes no difference). I'd argue getting the read the book straight from the page I bought them is pretty great.
I didn't bother with the android subsystem version but it would be an option if there is any limitation on the web part. I also have a bunch of old ebooks and scans from way before there were stores, and of course they were better handled by the windows apps (at some point I was using CloudReader on iOS, and it just disappeared).
