Pros and cons are really in the hands of the player. ...It just comes down to preference and feel. Its like on Martin's where they have several neck profiles and widths. No one is better than the other but one will feel better to you.
Play a few and see what you prefer.

Yup, it's all about your comfort level. For me, the difference is not big deal for most playing. But if I'm a gonna bust out with bare fingers on a tune, then the wider neck does help indiv fingers/notes when chording ring more true (especially the more "odd" chord shapes ...which for me is anything that's not a maj or min

) . But even then, I can adapt with the narrower neck.
It really comes down to how much you
like a particular gutiar. If you really love it, the slight diff in width will likely fade into an afterthought; if you don't find yourself bonding with it, the the different neck width is simply another reason for you to
not like it. It's more about what you hear and how you feel about playing said guitar: the measured width expressed in dimensions is just a number.
