I've used the DeWalt stack with great success. It does leave a slightly raised cut from the chippers, but it cuts very well.
Freud works with the Sawstop, but I've noticed when touching the blade, the constructiveness of the blade doesn't register on the Sawstop indicator as fast as other blades. I think it's their non-stick coating. Maybe I'm just imagining it, but I'd rather not take the chance that the brake might fire a few milliseconds slower.
