You can post https://www.reddit.com/r/hvacadvice/ . Need more info on duct. Otherwise hard to judge.

why do you change duct? 

ECM motor more expensive to repair down the road. Probably quieter and save some energy. 

My house uses Lennox. not your fancy ones. Not that good quality I hoped. Just single data point. I have some rentals with rusty looking Goodman ACs that keep running. Look up installer customer feedbacks.
