I've had my iPhone 8 for almost 2 years and now I'm working from home I've taken it out of it's case to fully enjoy the design.
Honestly, probably easier to hold a live fish than this bloody phone.
At least wit rounded edges the after-case size can be smaller.
Given the choice between a thin phone that needs a case and a phone that is as thick as a thin phone with a case that is more durable, possibly has a headphone jack and a slightly larger battery, I would personally go for the latter.
I agree the look and feel is WAY better without a case, but after breaking multiple screens, it's a case-life for me :(
