Given their return policy, I don't see any way to lose with the Rockwell 6. If you can afford it, I would go for the 6S -Stainless. As indicated, it's built like a tank. You can play with the plates. I have pretty much settled into plate 4 predominately, though I have used plate 5 when I have several days growth. For me, plate 4 is suitable as a daily driver.
Cheers!
