I like Wano Luffy and Raid Suit Sanji a lot. When I first watched OP in elementary school, I thought Luffy was the most attractive SH and Sanji was the ugliest though (Sanji’s Skypiea design scared me lol).
Looking at other comments on this thread, I’ve never been a huge fan of Zoro’s design, he has a very large forehead with no bangs and short hair. He is still attractive but his lack of interesting hair (a defining trait of anime characters) can’t make him my favorite SH male design. As of right now, I think Sanji’s usually suave outfits, floppy hairstyle, and cigarette make him the coolest design-wise. If Luffy keeps up how cool he looks in Wano though after the arc, he might become my favorite.
