It also depends on what the way the motor is wired up. But, as a rule of thumb, once you get past the entry level motors, you're doing alright.
There are a couple limits on peak power, the important one is the battery. But if it gets hot, the computer will throttle back to protect the motor.
All you need is to do is look at Nm. The Trek Verve comes with a 40 or 50 Nm motor, but the Allant 7 comes with 85 Nm.
The Allant+ 7 uses a Bosch PerformanceLine CX which I thought was 250W nominal motor.
Torque on its own doesn't mean much. For example, you can stand on the pedals with the brakes on an produce huge torque on the crank of a stationary bike but it isn't generating any power. The torque will go down as soon as you start moving. Gaining altitude or increasing speed takes power. You can get the same power with high torque and high gearing or lower torque and faster rotations with lower gearing. I don't see how a 250W motor can get you up a hill faster than one with more power, regardless of the torque of the motors. Of course, what matters is the power that can be continuously delivered and that may not be the same as the stated "nominal" power.
