It depends. The OMG guys are no good in use cases since they are all too much tech guys. You can well go with plain actors in all cases. You might use a business actor to distinguish them being some kind of VIP or what ever. It needs context documentation if you use them. In any case I recommend reading Bittner/Spence about use cases. It's a complex matter and takes time to understand (one year of practice at least).
