The Great Saiyaman
Cell saga is my favorite but he didn't have the overwhelming power that Frieza had. When DBZ started Frieza was already the almighty power. Everybody was shook of Frieza. We found out who the saiyans were and how their planet was destroyed. Learned about Goku and Vegetas fathers. And everybody had a decent fight up until that point. Also Frieza had henchman whereas Cell and Buu didn't. It was a hopeless feeling to beat Frieza. He was the most ruthless and powerful villain relative to everyone else.
Cell is my favorite because he was the most entertaining villain. The androids arrival was always so spooky to me and Cell just comes out of nowhere and crushes them. Vegeta turning SS, Gohan SS2, and Trunks made it my favorite. But Vegeta could have just killed Cell which made it kind of silly
Whole series is piff to me but by the end of Buu Saga I was like
You're gonna build up to Gohan being the hero from day one just to put the hero strap back on Goku, play Gohan out like a bytch? Goku had John Cena syndrome at that point.
