I don't know much about the e-bikes, but if you prefer the geometry of the Specialized bikes, you will probably like their e-bikes. My suggestion is to ride as many as you can and see which is most comfortable and easy to ride for you. Regardless of the name on the bike, it has to be comfortable. We are a Specialized family except for my wife. She preferred the geometry of Trek so she has two Trek bikes.
As was said early, go to your local bike shops. You are going to need service after the sale and with an established relationship, you are more likely to get quicker service and for minor issues, may get free service.
