Is there a big difference between 18 or 19 inch rims?

I'm looking at new rims for my stinger (2021 Gt-Line) I think the stock on the Gt-Line is 18 inch. And I'm looking at a new set that I like (also 18 inch) but does 18 inch look noticeably worse than new rims?

I live in PA and we love our potholes over here, so would 18 inch be better for everyday wear and more comfortable driving?
