OCs or Canon Characters?

I'm interested in seeing what the preference is? I tend to write up a lot of pre-written roles or canons to fit the story I'm working on. but i know a lot of people love bringing in their OC's as well.

 

I play a mix of both canons and OCs.

 

I used to really like canon characters, however, I've found I have more creative freedom when playing my own custom brew characters.

 

I play a mix, but I love bringing in OCs to a fandom verse. As far as a completely original world goes, I don't know that I particularly like the idea of there being canons to begin with. It kind of just feels forced.
