Am I crazy?

I had the gen 3 and loved it until it started having connection issues so I got another one but a Gen 4 I had the ring on for a few mins and it felt like it was burning my finger ??? And it also felt loose compared to the gen 3. I’m thinking about getting another gen 3 again do you think it performs as good as the gen 4? I wear and 8 and the gen 4 is too loose so I tried a 7 and it was way too tight I don’t think I could wear a Gen 4 especially with it feeling like it’s burning my finger .
