Track saws struggle with any repeated cuts.

I recently made a cutting board with many tiny pieces - 0.5" square, several hundred of them. With a table saw it's "run pieces through, rotate 90 degrees, run pieces through" - not fast but WAY faster than having to move the track saw every time, and that second cut is impossible with a track saw.

On a table saw I can do crosscuts. I barely ever use my miter saw (in favor of my crosscut sled on my table saw) unless I'm trying to keep the table saw fence positioned somewhere precise and need to make a crosscut in the middle of my workflow.

And speaking of the fence: The table saw is a precision instrument. The track saw is not. I set up my table saw fence once, eight years ago. I have never had to adjust it or look again. If I want something an inch thick I set the fence to an inch and make the cut and it is correct. I don't have to draw a line on my workpiece, measure, and make a mark. I don't need to measure the final piece with calipers to see if I got close enough to actually an inch. I can work quickly and efficiently.

Then there's bevels - am I going to buy a new rubber track guard for every different angle I want to cut, or am I just going to use my table saw and tilt the blade? If I want to be precise and always use a zero clearance insert, at least I can make those myself rather than having to buy rubber molding.

I own a fairly nice track saw (Festool TS55) and a pair of good-quality tracks for it. I own several expensive chunks of metal which profess to do things such as align the track at a 90 degree angle to my workpiece which I am unable to trust or even to get working consistently. I'm not talking "oh, this is 89.7 degrees", I'm talking "I can see with my eyes that's not square, guess I'll go get a combo square and a pencil".

I have owned devices such as the Kreg jig which aim to make it easier to do repeated rips with a circular or track saw and while if you don't own a table saw they're better than nothing, they're nowhere close to the precision, reliability, or ease of use of a table saw.

I love my track saw. I hate trying to pick up and manipulate 4x8' or 4x4' pieces of wood on the table saw and the track saw makes my life much easier - but that initial breaking down is all I ever use it for, because for every other task the table saw is dramatically better.
