I've used a lot of Android tablets, low end to high, and developed software for them. They're awful. Crashy, glitchy, bad battery life. I don't think we'll see a true iPad competitor until/unless a new OS enters the market—Android's had a long time to get its shit together, and evidently just can't. Wish someone would give it a shot, because I'd love to see that market better-served.
5 years ago I would have mostly agreed with your statements about android tablets, but since then Samsung has created a family of very acceptable tablets imho.
Maybe I'll try one from their newer line at some point. I haven't had a big pile of Android test devices around me on the daily in about 4 years (the consistent "Android's finally good now!" cry with each Android release and major-vendor product launch, followed by that never turning out to be true, for the entire decade I was doing mobile dev before that, is why I'd assumed nothing would have changed by now) so it checks out if they have in-fact finally made a good one (the older Samsung tablets were... not good) I might have missed it.
Last time I was guided by "no really this higher-tier Android thing is finally good, actually" advice was about a year ago, with the Nvidia Shield, though, so I'm... hesitant.
If I see one in a store, I may poke at it, read some reviews, see how their app store's looking these days for categories I care about. Could use a second largish tablet for the kids—or maybe a new one for me, and they can have the big iPad full-time. Having just one decent vendor in the mobile market blows (fucking Apple still won't add multiple profiles/icloud-logins to iPadOS, so annoying) so I'd be thrilled to discover that's changed.
