I would choose whichever makes sense for my business. Without pricing and reliability numbers, it's impossible to know which that might be.
The closest vehicle in Tesla's garage to this is the Tesla Cybertruck which looks bizarre, but is about $20,000 less than the nearest announced competitor. If Tesla launched a butt ugly Cybervan which was similarly functional and cost effective, you can bet it would be popular with the class of buyer who are shopping for e-Vans.
Right now I'm eyeballing the Cybertruck personally, in spite of it's appearance. Spending $20k to get a more traditional looking truck just doesn't make sense to me. The only concern I have is whether those high truck bed walls will screw things up.
