I have a Oneplus 5t that I still use for miscellaneous tasks, battery life is good, updates stopped a few years ago, but Lineage runs very well on it. And it was probably less then half the price of the iPhone XS Max.
When’s the last time you used an android Tablet? We have a Samsung Tab S6 and it runs excellently, there was a long period where they were downright bad, but if you don’t buy some super cheap no-name brand, they’re much better these days.
