Love my SG aluminum. Got the 42mm because I love big watches so the aluminum being lighter is a plus. I really never used the sport band because the outward curve of the band doesn't allow a close enough fit around my wrist. I immediately got a band similar to the modern buckle and finally found a leather cuff style.
Then of course, later they came out with the Hermes Apple Watch with a cuff band, lol.
I'm not particularly careful when wearing the watch and there are no scratches on it so the durability is the same to me.
