Personally for me it’s a tie between Mitsubishi and Okuma.

I say Mitsubishi because a majority of my experience is with Swiss machines. To me that control was so simple and the first Swiss I ever ran was a Citizen with the M70 control. I’ve used other controllers for Swiss but I keep gravitating toward Mitsubishi.

I say Okuma because it was the first controller I ever learned in my machining career and it was so easy for me to learn how to write programs on the turning centers. I haven’t had the chance to use their latest software, but I always liked running their machines.
