Between the one you have wrote I've never tried other than my SG Full Carve 180 which is a fantastic freecarving glass board at a resonable price, for us in Europe.
Very fast, using Alpine Replay I've found my average, substained and top speed grown 10kmh between my last 180 board. In any case it is also very forgiving and let you come out from bad situations very easly.
Just one defect , the topsheer seems to be very fragile. I've protected mine with a 3m trasparent film.
I've also one Full Race 170 which is a metal board, but due to the different size I cannot compare with the Full Carve 180 and I've tried only for a couple of hours this summer.
Just for information it seems to run like a 180 and carve tight as a 160 but it is just the first impression.
