I have both. Anticipating your next question; I like the Ti Walker better because it has better weight distribution for my tastes. The Dazzler is very even in its weight distribution - almost neutral. The Walker seems to put a bit more weight on the rims without making it feel heavier.
In terms of play, the differences are minimal. Both are as fast as you want to drive them and they have just the right amount of float when asked. Both are superb (it is YYR after all); I just find I like the Walker a bit more.
