My opinion...and it's based on actually trying it briefly when I was in the "temporary gara shop" is the answer is "no, and they are complementary tools". I made an effort to work with just the tracksaw, both with rails and with my MFT and it was not a successful experiment. If one only worked with sheet goods, it might work most of the time, but there are too many things that require smaller components or very narrow rips. I ended up grabbing a cut down PCS so I could do the projects I needed to do until I had the new shop building up. I still was using the track saw and uncharacteristically for me, the miter saw also got a lot more work whereas in the new shop it's "parked" and rarely employed. In the new shop building, my cutting gets done with my short stroke slider and the tracksaw is employed when I need longer rips on sheet goods since it's easier for me to get the sheet onto my flattening/cutting table and use the track saw than it is to try and do a conventional rip on the short stroke slider. So again, track saws are very valuable as a complementary tool to the table saw IMHO.
