What is a good m4 brand for airsoft?

My budget is up to $200 and I had a jg ak-47 which failed miserably so i don't want a jg gun anymore. I was looking at brands such as G and G, echo 1, king arms, and classic army. But which brand is the best? Also, post a m4 if you want to( I would really appreciate it). Thank you for taking your time to read and answer this question.
