Hyper DBZ/Z2 Style: Easily one of the most polished Mugen gameplay to date. It easy to pick up but hard to master and I absolutely love it for its pixel art, attention to detail, the crazy combo set ups, and Fan Service( you know the good SFW kind).
Z2i Style: Also known as Z2 Imitations these are not as polished as the original Z2 style but it still was created with lots of love for this style.
Amarimono/ASB Style: Gameplay base on a popular manga game. Check. Characters well done by wonderful sprite artist. Check. Has so many Jojo References that I can't count them all. YES! YES! YES! YES! YES! My only grip against this is that there not enough characters in this style.
