Choosing a Character

Hi im fairly new to the competitive sf scene and I’ve been playing around with the characters and I’ve decided to either main Ryu,Ken,Akuma or Blanka but im fairly knew so i don’t know really know what the styles of each character is or the way there played. I also don’t mind the difficulty and learning curves of the characters as long as i find one whose style fits me i can put the time in. So the question is pretty much what are the styles and way these characters are played?
Thx

The SRK wiki has a short description on the general playstyles and traits of all the characters. You might want to check that out: http://wiki.shoryuken.com/Super_Street_Fighter_IV_AE
