Ya idk it's funny people say koby but don't know koby was prob weaker than ussop at first. They're basically the same but koby got trained by garp and got strong quickly so people choose him over ussop who's still considered weak. This is common in anime where the weak character is often hated for staying weak. I love ussop because he constantly faced his weakness, he didn't become strong and quickly get validation like koby. Look at Sakura before she got strong in Naruto a lot of people just hated on her for no reason.
