As much as i like Super Perfect Cell, Broly wins here. Although Cell has many techniques which can help him out. Broly can pop out a Solar system buster or a Galaxy buster on Cell, and Cell is finished.
Strength = Broly
Durability = Broly
Speed = Broly
Energy Projection = Broly
Techniques = Cell
Intellect = Cell
Regen = Cell
Cell will have no time to make a move, Broly will be after him like a dog chasing a cat... actually, one punch from Broly will make Cell spit out the androids like Gohan did.... but even worst.
Lol... a punch to the groin will the the decided factor in this match.
There is seemingly no 'perfect' way to truly say goodbye. So I gathered a bunch of them!
