Are you writing solo guitar music or melody + accompaniment?

If the former, you might want to go for full detail, as that would warn guitarists where their fingers might have to go. (I'm not a guitarist, you'll know how they think).

If the latter, the added suspensions are going to happen anyway, and extra detail will just get in the way. A violin/accordion duo might want to play your stuff and they aren't going to thank you for telling them that the melody makes an add6 chord with the accompaniment.
