Which system? I'm confused

Hi,
I have brushless XRAY XT8 that ran great for 3 month with EZRUN 80A and 2350KV EZRUN motor. (I can post a video)
I ran it with 4S 20c zippys. Performances were great with no issues at all.
I was very happy with this setup until on the last weekend my ESC went on fire and almost melted completely.
I don't know what was the root cause for that, could be a short, moister or internal failure.
Now I'm looking for new ESC but while looking around the threads I noticed that all brands have reliability issues.

I don’t mind to invest extra $$$ for MMM or TEKIN but if at the end its going to end up with a lot of smoke I prefer to stay with the cheap EZRUN.
I leave out of the U.S and its very difficult to me to utilize the warranty that the above brands have.
What do you think? Should I return to EZRUN or put my money on a new system?
