I like my Freak kit, shoots stright and just performs well. It's really a hard choice between the two.
With the Freak kit you have the choice of multiple bores with a 3 pieces- a back, front and bore. This makes it easier to change to a different marker if you decide to buy something else. All you have to do is change the back. The bore inserts give a better paint to barrel match and is more accurate.
With a Dye you have two pieces, a back and front, with no option to change bore size without having to use a different back, meaning your paint to barrel match isn't going to be as good.
If you're going to play speedball and scenarios, go with the Freak. If you are going to play scenarios, go with the Dye barrel.
