looks like you agree, since your commuter bike is not from Specialized.
I would simply say Como SL is not the e-bike I would like to own. Especially as I don't crave for a belt drive. (Como SL is a female-oriented city e-bike but I am a suburban & touring type).
My definition of a commuter e-bike is one that allows you getting from point A to B possibly fast and with no sweat on. A hub-drive motor e-bike capable to move up to 20 mph without effort makes a perfect commuter e-bike. Again, I'm no commuter, so I let my close friend use that e-bike for a couple of months as he needs it badly.
My Vado 5.0 (the 45 km/h version) is the e-bike I have used the most (around 10,000 km on its odometer). It lets me making any ride I like: from a fast ride for a coffee with a friend (28.5 miles in 1h 30 mins round trip) through a 104.4 mi touring trip in the flatland to a 77.7 mi/5060 ft mountain trip. The only thing I have to suffer with this e-bike is the weight of 52.8 lbs, which makes it hard to carry it upstairs to the flat I'm currently living at.
For the practical reasons, I got me a Vado SL 4.0. As it's 37.4 lbs e-bike, I can carry it with a single hand upstairs and keep it in my flat. I use it for daily neighbourhood rides but also for leisure long distance trips. Vado SL contributes the best to my physical shape, and is my choice as the perfect second e-bike. It is amazing I can control both bikes using the same software (Mission Control or BLEvo). On the latest ride, a female friend of mine rode her "big" Como 5.0. As I discovered she might run out of the battery, I connected to her e-bike and applied Mission Control "Smart Control" feature, and could have stopped worrying about her e-bike's range.
