Hmmmmmm....a 3-way tie. I do all my rev-clouds in PS on a revcloud layer. With as many as 15-20 vports on some sheets, layer management is already a nightmare, I don't need THAT added burden.
BTW When is Autodork gonna get their act together and let you dim an object in split (2+) vport? A 30' piece of C10X20 with seven 1 5/16 holes needs multiple vports....(or its own sheet for petes sake!) to dim. PITA!!
