I have a GenZe 102 that is torque sensing. Indeed, you stop pedaling, it stops helping. I find the torque sensing will help up to the PAS level. On flat ground, little help is needed. Going up a hill, more help, higher PAS, is needed. Higher PAS on level ground does not affect anything or give too much help. It can cause abrupt starts, though.
The GenZe Nearly New bikes are quite affordable.
