If, you are not concered about playing chords that rely on the thumb as part of the chord formation structure (i.e. the 'thumb' F chord, and other assorted thumb style positions,) then the extra "leg room" you get with at least a 1 3/4" nut width is great, and, it can improve your accuracy of "nailing" the chord shapes.

I kind of started backwards. I initially got a guitar with a 1 3/4" nut and everything was fine. But as my playing developed and I began incorporating the thumb into so many of my chord positions for the styles of music I play, the stretching to accommodate the thumb with the wider neck was killing my tendons, and not giving me clean sounding chords.

I've since replaced all my wider necked instruments except one, with guitars sporting narrower 1 11/16" nut widths, and my wrists and tendons thank me for it everytime I play. I only play the one remaining wider necked one for flatpicking solos and rhythm (and no thumb chords, except the F chord.).

So....if, you don't use thumb chords, by all means go for a wider neck.
If you do use thumb chords a lot, and you have average sized hands, stay with the narrower neck (and even consider a neck shaving)...but as others have so aptly stated here, it all depends on what feels good to you, for the type(s) of music you play.
