Do yall think it looks better to buy pants big enough to wear with your belly tucked inside of them? Or is it better looking to wear them with your belly hanging over the pants?

I'm predominantly a casual jeans guy, although Im trying to get more stylish. I find that my underbelly gets rashes from the leather treatment chemicals or the buckle on the belt. I wear an undershirt always now, which helps but got to wondering how it would look if I wore them with my belly tucked in. I've looked online and have gotten very mixed reviews. I tried it with these size 40s I have but the muffin top looks even worse imo. It could be that the rise is not long enough though.
