I’d say it’s more of a learning curve question. With a swiwel you get good results most of the time but if it doesn’t work as you need there’s nothing to do. With a solid construction you need to learn to manipulate it efficiently but then it’s that you can use it for any shape of skull. TL;DR convenient ≠ better
The head isn’t on a hinge so you have to manage the angle yourself
Do they really not make any with a swivel head? That’s a pretty useful feature imo, and certainly would be easy to design for on a safety razor.

I’ve literally never once had a swivel head razor that didn’t work.
It really seems like a stretch to make this into a skill issue lol
