Does anyone prefer the rounded iPhones more?

Definitely. The X design era was the pinnacle for me. I do not like the sharp corners, they are uncomfortable to hold and basically force you to always have a case.

The iPhone XS might be the best iPhone so far - unfortunately no headphone jack, but it had the rounded design and still had 3D Touch.

Regardless, I've decided expensive phones are no longer worth it at their insane prices, and I'm switching from my dead Galaxy Fold 3 to a cheaper Realme which should arrive tomorrow. I'm setting myself free of caring about these high end phones at all.
