I have tried many times over the years and always went back to iPad. Ignoring the ecosystem (since that's an obvious advantage) here is my experience:
Android Tablets
I used to work for Google so we were issued the Nexus tablets, and I personally owned a few including Microsofts foldable phone tablet thing.
The devices are... fine most have worse specs then iPad but some of the top ones are similar or even better in some aspects (bigger or better screens (before the latest OLED in the M4).
The software blows, hardly anything is optimized for tablets and most are blown up phone apps or 'tablet apps' with tons of wasted space that is used much better on iPad. Battery is worse in my experience and the performance is really poorly optimized. I never had a good experience with any android tablet, the closest one was Microsofts but again the core experience is janky and breaks randomly.
Windows Tablets
I owned several surfaces including the RT, Pro, and various iterations after. It's great because you can run full windows apps on them with minimal fuss, I actually liked the Windows 8 start menu for the tablet was nice and easy to use. The problem is Windows is extremely disjointed with a bunch of ancient cruff mixed in with modern sleek stuff. The UI scaling is and continues to be atriocus with some apps obeying it and other apps doing its own thing, so some elements are gigantic others are microscopic. Again it reminds me of Android where the experience is just NOT polished at all.
That being said if I had to choose a non-apple tablet it would continue to be the surface, I can even run android apps on them to a pretty good degree and I love the built in stand and ability to expand storage. I hate the Microsoft keyboard because it uses the rat fur material which gets so dirty and nasty but I do like the technology built into it (ability to use it disconnected from the surface, and its different attachment points)
Apple Tablets
the iPad is a phenomenal device for having a really solid and well thought out core experience. I find it to be ironically less stable and reliable then a Mac once you start doing Mac things like using an external display and multi tasking a bunch of apps it would regularly crash the whole windowing experience which is a huge disappointment. iOS 26 beta 6 so far seems to have fixed some of the poor experiences I had when using an external display. Apple's latest updates (namely the changes to Files (like adding it to the dock, 'Open with'), as well as adding Previews (finally) really make it a solid device for me since I use previews constantly for work. I use my iPad daily in addition to my Studio M4 for development, working with clients, demonstrating our app, reading the news while in the bathroom, etc.
tl;dr
No iPads are a solid 1st choice for me, if you twisted my arm I'd get a surface. Android is not competing at all in the tablet space as far as I am concerned. It's really a half thought that is poorly baked together. Even Google is giving up which doesn't bode well for the future of android on tablets:
