charles the first questio you need to answer is,,can your saw accept a stacked dado blade from those you mentioned. i wasnt as informed early on and knew i wanted a knew dadao bought the frued and it wouldnt work on my old craftsman saw so i now had a dado and no saw that would run it ..so look at your saw the arbor needs to set up so it wil work.. then as for who has the best i still have the frued and love it but they are others out there that are just as good.. not gonna compare havnt only had the frued ..others willchim in and tell you there thoughts another thing to look at is a 6" dado head runs better on smaller HP saws and you get a smaller shelf to clean out if you run a stopped dadao on a project!
If in Doubt, Build it Stout!
