With the Festool TS55 and a track - yes, it is. As good as a table saw edge.
And if you ever work with MDF you will definitely appreciate the Festool Dust Collection over a skillsaw and straight edge. I know that from experience.

+1 for the dust collection with MDF. My bride was not too happy with me putting MDF dust all over the jogging stroller via my table saw and/or a circular saw (with shooting board). She was floored after my last project with how clean the Festool left the garage.
