Best tablet to mimick cell phone?

My dad can't see super great and has a s20 ultra. He basically plays games, texts and uses messenger on it. What's the best tablet that would match the specs of his phone? I don't want to get him a laggy piece of crap, but he obviously doesn't need the best thing out there. Also want it to be able to sync his texts which is why I'm looking at pixel/Samsung. Thanks!
