Guess that depends on what side of the fence you're on. I flew 135, and refuse to ever go 121. Home every night, actually enjoy the planes I flew, even if they were piston twins. Freedom of operation!!!!! I've moved to a part 91 job, pay's better, turbines, benefits, so obviously a move up, but I could go back to 135 if I had to and know I was being paid what I was worth!!!
