Linux is very good, but from my experience, not for game development, I have a history with linux, for me, when it comes to making game tech, specially on the low back-end graphics programming... it's painful as hell! Debugging is not trivial, gpu profiling is innacurate and drivers from certain vendors like AMD performs way worse on linux than windows. It used be better, but when android came out it seems like the big OEMs shifted their priorities thanks to the new embedded systems.
