Depends on what kind of work you do. 90% of what we do gets done on the RAS, but if you cut a ton of sheet goods the TS will do, but even then you needsroom for an outfeed or just room to handle the material. In my small shop sheet goods are a pain even on my 10" Unisaw. Makes me consider breaking sheets down on sawhorse in the driveway with a skilsaw and making finishing cuts in the shop.
