Couple things to keep in mind:
MT1 Tower is only 52 inches tall, so if you do not have a deep boat, you could have a head room issue, especially if mounting speakers.
The benefits of the MT1: super easy to install, collapses very easy, solid tower.
Vapor Tower is 55" tall, so you gain more headroom with the Vapor. The Vapor is simple to collapse. Vapor will most likely not accommodate a factory bimini either. Vapor is a bit more labor intensive to install.
Benefits of Vapor: Easy to collapse, Great Style, Solid Tower, Height of Tower
If you have specific questions, let me know. We install both of these towers all the time.
