Similar questions, especially about things like cutting tapered table legs, have recently come up over at the Festool Owner's Group.
I don’t have a lot of table saw experience, and my Dad’s got a few shorter fingers because of some table saw experience, so I’ve no desire to work with a tablesaw that’s not either a SawStop or a euroslider of some sort. Among other reasons, that’s why I went with the Festool TS55 saw and MFT table.
I think for the most part it’s about thinking about your cuts in different ways. There are some dadoes I couldn’t cut with the Festool saw that’d be easy with a tablesaw, but I can cut them with a router. Technique for tapers took a little practice, and I’ll probably be refining my technique on that as I build more tapered leg furniture. Accuracy is mostly a matter of how much you’ve let the rubber strip on the rail wear, but since you can move it fairly easily, accuracy is easily within visual limits (if you can see the line to put a razor blade in it, you can push the rail up against the blade).
There are certainly some cuts that are faster or easier on a tablesaw, and some that are faster or easier with the Festool saw, for me the safety and portable shop make the Festool win, and if you’re comparing against a sub $1000 contractor’s saw, I think the scales tip towards the Festool. If you don’t want the dust collection, you might also look at the EZ Smart rails and a matching saw, but the Festool gets so much stuff right that I’m a convert.
