I do think each player is going to have an optimal/preference for a certain neck width. 6 string necks feel very strange to me and much too narrow. I like playing 8 strings and most of the time, that's what I'm picking up. But when I do pick up a 7-string, it's like coming home. It just feels so much more comfortable, even if the scale length is the same. It's not a huge deal and I quickly adjust back to the 8-string, but it's definitely a thing for me.
