I think their intensity is very overlooked. The only Mack launches I've been on are Helix and Time Traveler, but both have some very intense moments. Helix has a few crazy ejector airtime moments, the transition into the helix has awesome ejector and laterals, and a few of the banked turns have some really good positive Gs as well. Time Traveler's drop out of the station is madness and the twisty hill offers some great airtime and laterals. The first launch also has a bit of punch to it.Mack launch coasters are not intense, anyone expecting great intensity will be dissapointed. I think that's why Icon got mixed reviews from some who were expecting it to be intense. They are fun, smooth, comfortable & floaty.
While Mack launches themselves aren't too powerful, they still make rides with good intensity, and in my opinion have the perfect balance of forcefulness and rerideability.
