In the last three years, I have gone through three different ebikes (still have the last two). At the end of September, I received a recumbent trike (ordered it in June). I absolutely love it. It is so much more comfortable, that I can enjoy riding much further. With the trike, I typically ride 20-30 miles, almost every day. I have also ridden much further on it.
I bought a Priority Current about a year ago, and it is an excellent ebike, especially for the price. I added a better seat, and a suspension seat post, as I like to do long rides. After riding the new trike, I'm selling the Priority Current.
As to which trike to buy, you need to do some research (I did a lot), then find a dealer, where you can take a long test ride. There are many brands, options and prices. I decided to go top quality, and bought an ICE Adventure with the Shimano STEPS EP8 motor. I also went all out for suspension, mud guards, padded seat, Rohloff 14-speed hub, extra battery, etc. All of these options almost doubled the price.
One big trike feature to consider is "direct steering" vs "indirect steering". Test ride one of each on a bumpy road at high speed, if you can. One reason I went with ICE is the indirect steering (there are other brands that also have it). Like everything, it's personal preference. Suspension or not will probably have more effect with direct steering.
One option that I didn't need, but some do - "assist handles" to help you get into and out of the recumbent seat. On the ICE Adventure, I have the seat up as far as it will go, which still is somewhat reclined. Some trike models have seats that are more reclined than others.
One thing that I changed immediately was the pedals. The trike came standard with Shimano clipless pedals. The idea is that with matching shoes, you clip in to the "clipless" pedals. This keeps your feet from slipping off of the pedals. If you are moving fast, and your leg is caught beneath the trike frame, you could be seriously injured. This is called "leg suck". There are several options, other than clipless pedals and shoes. I went with very long and wide mountain bike pedals (RockBros from Amazon). The studs on these pedals grip my regular shoes or sandals very well. In 850 miles so far, I have not had my feet slip off of these pedals. The Trike Hobo guy on YouTube uses similar pedals that cost several times as much as what I bought, but his experience matches mine.
YouTube is a goldmine for reviews and ride videos. After identifying possible candidates, spend some time watching videos. This will help you narrow down your choices, before looking for a dealer and a test ride.
