Akainu (Sakazuki) well he isnt really a villain, hes just doing his job as an admiral but he IS and antagonist. so hes my favourite "villain". Hes pribably the most hated op character just because he killed ace
For Dragon Ball, most antagonists are not even villains, just people with different goals that Goku brings over to his side later on (ex: Tien Shinhan, Piccolo, Vegeta, the Androids, Buu, Beerus, Hit, Jiren, Broly)
Favorite villain: Cell (more creative than Frieza and Buu, not as stupid as Zamasu, and not a side character like Dabura)
Favorite antagonist: Vegeta (great character arc overall and stayed with Goku through everything)
