Adam, in all probability you need look no further than your saw blade. Do you have a dedicated crosscut blade (60 or more teeth) or plywood blade(many teeth)? There is no blade I know of that excels in both cross and rip cut.
As for dados, again, what type of dado blade do you have. Dado blades are like dogs. They come in all different sizes, shapes and dispositions (tearout). A Freud super dado will cut as clean a dado in plywood as you would ever need or want. Pay what you need for good dedicated blades. You won't be sorry.
