Which Beat Em' Up series do you prefer?

I understand there are many more great series. But of these three which do you like more? considering all games in series which are beat em ups.

Out of those three, double dragon. As a kid though I played the Power Rangers game and it was REALLY good. (not the movie game)

Can't beat the turtles, but I did love Battletoads

TMNT wins on the original '89 arcade game alone. After that, Streets of Rage.

As a kid, Streets of Rage ate up most of my childhood. Still love the setting and music.

Double Dragon 2 = great

Streets of Rage as it was what I grew up on.

TMNT sir.

I personally hate Beat 'Em Ups. They all controlled like ass, never have a block function (and when they do they are worthless), and... well, those are my only complaints, I guess.
 
That said, the only one I ever enjoyed was Turtles in Time.

Out of those, Streets of Rage. My favorite however is Fighting Force on the PSone.

Where is Kenka Bancho: Badass Rumble?

 sor2 is amazing.

Streets of Rage is awesome!
