I had a 2017 Chevy Bolt and it is an amazing commuter EV. They are one of the most efficient EVs, getting mid-200 mile range out of only a 60kWh battery, with a rating of 3.5-4.5 kWh, for an EV from 10 years ago, it is still one of the top rated for efficiency.
The Aptera is claiming 10 miles per kWh, which if they can do it, awesome! But I'm really skeptical, plus even if they can, it's a 2 seater that looks like if an F150 sneezes it'll get crushed like a beer can. Whereas the Bolt has room for 5 and at least ample crumple zones(I've seen some crumpling first hand ) Also as a 3 wheeler it basically has 75% the grip of a 4 wheel car so handling/stopping may not be as good.
The Slate is rated for 150 miles with the standard battery at 52 kWh and 150 mile range so about 3 miles / kWh. This isn't bad for what's essentially a square brick moving through the air, and better than say a full size EV truck that generally see around 2 miles per kWh. The Slate also only seats 2 but has a 5 foot bed and frunk for storage, also it looks pretty sweet.

Edit, the Slate can also become a 5 seater with the SUV kits, and the fastback may have better aero for improved m/kWh.
