I stick built a bar with my GSS system, in about a day and 1/2. I am building my kitchen cabinets with it as well. No need to cut twice, just measure and cut and I am done. No issues with time or repeatability using some simple measuring sticks. I get good clean cuts and edges. Much easier to take from truck to the saw horses. I do use my TS for the drawer material, but the cases themselves are all done via the GSS.
My brand of choice is Festool, but others work as well.
