Reno 6 rm2400, Reno 5 Pro rm1800.... which one is better phone or better value?

I check the spec side by side they seems pretty similar.

The differences I can tell physically is that Reno6 has iphone12/13 square side design. while 5 Pro has curve edge screen.

Reno 6 has plastic back, Reno 5 pro has glass back.

Anything else I need to be aware of? In terms of performance?
