I've probably used a grigri to rap well over 100 pitches. It's no more, or less safe than at ATC style device... just different.
As Marty mentioned it is a single strand device so that limits it's use in most normal situations. It's failure modes: improper loading of rope into the device, improper system rigging, and letting go of the break hand are identical to the potential failure modes for an ATC. Knowing the device's function solves #1, knowing that it's application is for single ropes only solves #2, and backing up your brake hand with a prussic can solve #3.
Although I use it to rap extensively for fixed-rope situations I almost never bring it with me in day-to-day climbing. To clean and rap a pitch you'd either need to:
1) feed an end through your rap point, tie into it, and feed the other side to the GriGri... thereby lowering yourself down the pitch (
drawback is that the rope is moving... so make sure it's on metal and not soft-goods. drawback #2 is that you'll have no way of confirming that you have enough rope to rap the pitch before committing... so tie a knot in the free end and hope to god that it doesn't get sucked into a flake as you rap and it gets pulled up. )
or
2) simul-rap with someone else using a GriGri (
drawback is that this is generally accepted as a trickier situation... not to be attempted unless you... and your partner know exactly what your doing)
Both options are more of a pain than just tagging along the extra 60g or whatever the weight of an ATC is.
If you wouldn't rap with it than I certainly hope you wouldn't belay with it either. Right?
