i think the best thing about the track saw is trimming printed panels. for flatbed work you can guarantee that you'll have the print always in the exact same spot, or perrrrrrfectly square. by printing trim marks, you can print and not worry about the perfection. this is what counts the most to me. tracksaws cut to the zero mark. you set your track on the line and cut, no offset measurements. this also means track saws don't depend on a fence to maintain square so you can cut the around the print regardless of the oblique line or a skew. fences on table saws force an often unwanted parallel cut, the plumb/square needed to get a sheet trimmed in a panel saw doesn't work either, and the offset needed to get the blade in the right place with an after market fence make all these other options inferior plus none of these saws can cut as smoothly leaving a perfect edge especially on sheets with delicate coatings and laminate. if you need to cut an oblique 1/8" off of the edge of a mounted or printed panel, that would be a doozy except for with a tracksaw, it's like using a giant pair of scissors. there is no holding your breath that you don't jog the sheet just slightly and mess up the cut. often times, i'm having a side conversation while doing these critical cuts because you just can't mess them up. panels saws are great for knocking down basic square cuts, tables saws are great for repeating cuts (unless they are really big/long cuts then the track saw is better), track saws are great for precision trimming. i've had all three cutting options in my shop and in the end, you see the panel saw getting the least use, then the table saw, and the track saw being used the most often.
