I do not know either saw, but, my opinion is that if all else is equal, I would take the ability to use a Dado set is important to me. OK, so maybe you can't do it on one pass, but you can nibble a bit at a time. Then again, if the other saw is clearly superior in some other way (like a better fence), you can always use a 1/8" blade with appropriate cutting edges (so they cut square) and nibble a bit out at a time. I have done this for things such as drawer bottoms where I have it cleared in a few passes and that can take less time than setting up my Dado set.
