Are Xiaomi tablets good options even if they're set to die soon?

I had, for a week or so, a Samsung tablet that would flash in red everytime the brightness would lower. I returned it, and now I'm looking for another one. For this reason, I wanted to ask if Xiaomi tablets are worth it even if they don't get 3-5 future updates like Poco Pad, Redmi Pad Pro and Xiaomi Pad 6. I want it for studying purposes, in case you wonder what I want it for. I'm also connsidering iPad 10 256gb or Air M2 128gb, but they're way too expensive for what I want them for.
