This is tough to answer because there are so many variables. For example: home owners vs. renters vs. apartment dwellers, solar charging, time-of-use billing, etc. And so much is changing with things like vehicle to home (V2H). You'd (the generic "you") be better off asking about a specific situation and use case. Otherwise it's a bit like someone asking which car should I buy.
I had a Bolt, and now have an ID.4. I've never needed to go from empty to full overnight, so any Level 2 (L2) changer would work for me. I own my house so it was easy to add a plug. A plug limits me to a 40 amp charger, but as I said that's not been a problem for me. Perhaps if I bought a Lightning or Silverado with their massive batteries I'd get a hardwired unit that can charge at more than 40 amps, but that's use case specific.
I have a friend that lives in an apartment, but has free L2 chargers at work and that's worked for him for years.
Once V2H cars have been around for a few years and chargers and switches catch up, then It might be time to switch my charger.
