I haven't heard the TiAL setup in person, so it's tough to say. The Turbosmart Supersonic kit is pretty loud, however, and is a bit better dialed in for the EcoBoost trucks out of the box. I know a few folks that got the TiAL have had to swap the springs out in order to get the things dialed in perfectly, while the Turbosmarts tend to behave themselves pretty well as a drop-in.
