It's much safer and better to pull off a rez with full HP and GP. If you get guard broken, you can at least run away and try again. On the other hand, it's an instant game over the second someone even glances at you. As most quirks that can interrupt a revive at will don't reach very far and/or do not go through walls, being at full GP/HP lets you to pull off more revives more often by being able to tank through it because the quirks that do reach very far, tend to only deal damage and have very little down power.
