The guitarist does not need to necissarily be a metal guitarist as in they can play jazzy guitar but they need to be in a metal band.
For me it is probably Hetfield. The way he can still sing well while playing quick, technical riffs and his implementation of the hybrid picking technique makes him an inspirational rhythm guitarist to me. Dave Mustaine is also brilliant, however Dave cannot sing for shit while playing.
If I was honestly asked who I think the best metal guitarist is, I would be hard pressed not to say Jeff Waters, he is a god.
EDIT: To back up that statement on Dave, watch That one night, Dave just cant hit high notes live on stage, though his guitar is perfect.
