While Goku does admire Bulma's beauty, he's generally oblivious to the concept of comparing women's attractiveness. His focus is on fighting and his friends. He doesn't express any strong opinions about Bulma's beauty in relation to other women, nor does he try to convince anyone of her superior beauty.
There's a scene where Goku admires Bulma's new outfit, but it's a simple compliment and not an attempt to elevate her above others.
It's important to note that the Dragon Ball series, while filled with humor, generally avoids making comparisons based solely on physical appearance. The focus is on character development, friendship, and the strength of spirit.
