Production Apprentice has an excellent article on moving back from Final Cut Pro 7 to AVID Media Composer. He likes the move and really gets back into using trim mode, which is barely used on FCP 7, though still likes some things about FCP 7.
I feel about the same, I still like certain things about FCP 7 better, but now that it is EOL, it is time to really to get back into Media Composer, though I am also really enjoy Premiere Pro quite a bit.
