I want both but I only have enough for one, what do you guys think would be the best choice?

One is a MMO shooter. The other is a fighting game.
Buy the one that appeals to your preferred playstyle more.

I personally think that Defiance looks terrible, but you might get more hours of play out of than Injustice.

Based on reviews around the web, Injustice seems to be getting much better feedback from critics.

Honestly, I wouldn't get either.

Not a fan of shooters, so Defiance is out. As a Huge DC comics fan (see my avatar) I would love to get Injustice, but, unfortunately I really svck at fighting games.

My favorite game reviewer Angry Joe gave Defiance a 5/10 (average) rating. If the game had not been so damned buggy in Beta (it was literally unplayable because the patcher for it would fail 99% of the time) and in its innitial release it probably would have gotten a 6-7. So it's nothing really special if you go by his review.

On the other hand he has not played Injustice but he did play the Beta for it and it seemed to have a lot of good potential and he said just from the limited Beta it was a lot of fun. So if you like fighting games I would probably say go with it.

Defiance has had some server troubles and looks okay at best. Go with Injustice I guess.

Defiance

I got Defiance after watching the show. I don't understand these poor reviews, this game is very fun and I love the concept of the show and the game influencing each other. I do wish the race and origin you picked gave you different abilities or at least impacted game play in some small way. I also wish there where more races to choose from and that the game was an RPG. The reason I asked is because I want both games and like pretty much all play styles so play style really wasn't a factor for me.
