As a Galaxy Tab S6 Lite owner, I can confirm it is an excellent Android tablet. I don't use it for much other than browsing the web and editing novels, but for those functions it is great. Before then I had a Galaxy Tab A10, and it was fine, but a little sluggish on the UI. And I missed having a stylus too.
For my other work - I work for the government in taxes - I use a Surface Pro 6. I also use a (different) Surface Pro 6 for my self-employed writing/editing work, and do a bit of editing on it with the Surface Pen, but the 13 inch screen is a little big for long-reads. I'm generally a fan of Microsoft's Surface line - they are robust and sturdy, work well and feel premium. Windows is also a decent tablet OS at this point, though it has nothing on iPadOS in terms of tablet functionality.
Depending on what you want to do with it, I'd recommend a Surface Go/Pro or an iPad as a tablet, unless all you want is a reasonably fast tablet for browsing and basic pen work, in which case there are some very good Android options.
