It depends on what you're making. If you're making a networked shooter ... well you can make it a lot faster in Torque. The game that I'm making with Torque ... I couldn't imagine the amount of work I'd have needed to do with Blitz to bring it to the same point in Torque. On the other hand there's some stuff that I'm sure would take longer in Torque than Blitz. Right tool for the job and all that.
