Thinking of upgrading to Seqouia, how does it run? (It's mostly for Final Cut pro)

I have seen similar posts but I'm just wondering what others are thinking plus any good or bad points to consider? I'm mostly worried about the touch bar and battery life?

It's always hooked up to a second screen with mouse & keyboard however I primarily use the device for video editing. Trying to get at least another year out of it if I can before upgrading.
