Make sure to get an e-bike with a torque sensor especially if it is a high wattage model... even if you have to lower your standard on top speed.
I did some digging to find a more impartial video on the two types of sensors with demonstrations and explanations:

With what I've seen and searched I support to go for a torque sensor, because it will definitely fell more natural blending with your desired speed as a result of pressure you put it,
Cadence seems more like a constant speed regardless of your desired speed or effort, as long as your paddle it goes on its own speed starting from No.1, and it's seems risky as well, in a busy road you only have to paddle manually to keep cool, no cruse just effort

I'm actually starting to get interested in getting an E bike too
