Absolutely! When I meet somebody doing something better than I do, I love to integrate their take on things to improve my GMing. Why would I want to stumble through a bunch of bad ideas when somebody else already has good ideas to borrow? Heck, I've only ben GMing for 23+ years and I still enjoy learning more from other people. Heck, that's part of the reason I hang out online here. There are a ton of GMs and I am always learning something a little new to try out. I try to put out the occasional idea that others might find useful too. I would consider it quite a compliment to have somebody say they used one of my ideas and it worked for them. Hmm, maybe I need to remember to thank the people whose ideas I snarf from? What goes around comes around and all that. 
If you have a personality conflict with your old GM, that's fine. Still take the good aspects of that relationship and use those. Why be so bitter that you can't see the good things he did?
