I have a SE and a X, and have ridden every motor brand except Bafang.
I find them all more similar than different - the Brose being the quietest, but wind noise at speed is louder than all of them.
I absolutely love both of mine - got the Explore a few months ago, liked it so well I just picked up the Trance.
From what I hear, the new 2020 X motor is super quiet, and provides higher cadence support and torque. Win win win all around.
The only thing I think holding them back today is lack of a larger battery pack. For me the 400w in the Explore is fine, and the 500 in the Trance is as well. But I'm old.
