It depends on what your looking for in a boot..
we sell the Full Tilts all day long, mostly to old people, because they know the history of the boot..
but now, the Full Tilts use Inuition foam liners, which has been being used by 32 snowboard boots for a while.. I'm sure you know, they are fully heat moldable, from the toe to the calf, and the cord system allows for a completely free flexing boot, where the Dalbello boot is a 3 piece boot, and they are super adjustable, and very awesome as well. The best selling Dalbello boot for us has been the Krypton Rampage, but this year, we sold quite a few il moro's.. the best selling Full Tilt boot has been the bumble bee pro.
My advice, would be to go to your nearest shop, and try them both on, because they are both absolutely great boots, but one is going to fit your foot better than the other.
hope this helps.
