Which is better Mturk or Odesk?

Both of sites are genuine and good. But in Mturk, if they will suspend your account, you cannot work any of their HITs (Human Intelligence Tasks)whereas in Odeks, there is an ample chance to apply and get for new jobs.

I, myself prefer mturk as there are a lot more jobs with them and I have made really good money with them so far. I have actually cashed out a large sum with them about four times already. I do all the little jobs for a few cents but then do some writing and transcription jobs for them as well. I think if you do the writing and transcribing jobs you have a chance at making more with them. Odesk I think is a bit harder because those jobs are a bit scarce and I just have not really had much luck with them. I have applied for a few but never heard anything back and with mturk I always get good jobs and even get requests to do more jobs outside of mturk as well.
