Barre. Never found a situation where I needed to wrap. But I suppose if you play blues, it's part of the tradition. Actually, if you keep your left thumb behind the neck rather than using your thumb to hang your hand on the bass edge of the fingerboard, barre chords become pretty easy.

Ever try to do a bass run while holding a wrap? Bloody impossible. But it can be done while holding a barre.
