I also just prefer the feeling of the #BBSHD to the #TSDZ2, but this is also some good rationale: https://jonsully.net/blog/ebike-cadence-vs-torque-motor/
If you want to feel like you're always getting a workout and always pushing, you want torque-sensing.
Cadence-sensing lets you choose whether you want a workout or want to rely more (or entirely) on the motor, because you're trying to get somewhere. I appreciate the choice.
(Of course low-quality cadence-sensing systems suck, but so do low-quality torque-sensing..)
