I often read on my Kindle and on my Android phone and my prefered reading app on the phone is Moon+, which won't sync with my Kindle, of course. I've found that syncing between them is trivial if I simply pick a short phrase as I stop reading and then use text search on the book in the other device. That's usually faster than syncing automatically as long as I don't forget the phrase. The phrase in my current book is "cinders and bits". Simple enough to remember and the text search gives me enough context to easily pick the right one if it occurs more than once.
That said, in the past I had an Ipad and an Ipad Mini and I sold both of them. They were just too much trouble in too many ways. They were nice, fast and reliable devices as long as I didn't want to do anything other than the same stuff everybody always does. Sometimes I like doing my own stuff.
I've been using Android tablets ever since. I do have a Galaxy Tab A 10" with S Pen and it's an excellent tablet. I suspect you're looking into the 8" version and I don't know much about that but I've had a number of Samsung tablets over the years and all have been excellent.
My real preference is for Asus tablets. They've also been excellent and they modify Android less and that makes them more straightforward to use. I got this Samsung because I wanted one I could draw with and it's great for that. It gets the best battery life of any tablet I've owned. The thing I don't like about it, and this has been true of my past Samsung tablets as well, is the capacative back and app buttons that I'm always accidentally hitting and finding myself out of whatever I'm doing. Dumb! Dumb! Dumb! Samsung!
The newest Asus tablet seems to have done the same thing. Lots of dumbness around.
