I don't know the TurtleWax you're talking about in particular, but my TW experience is that it's a paste that needs to be carefully applied, allowed to dry, then buffed off, and which can leave white residue in crevices and crannies. Spray wax like the Pledge is wipe on and off, and does not leave residue or discolor black bits, as auto paste wax can, and there's no waiting for drying or careful application. I just spray the wax on the rag, wipe down the bike, flip the rag over to a dry area, and quickly buff to sheen. Quite fast, really, and certainly faster than paste waxes in my experience.
