Never tried the SS, but it does get good reviews. I had the RS DB laying around when I got my first HDTV, and it out performed all the other antennas at the time (even the amplified "HDTV" antennas) - none worked as well.
You'll get all the channels - ABC, CBS, NBC, PBS, FOX, WB, UPN in HD. If you go the outdoor antenna route, you may pick up some Columbia stations as well. I get Columbia, Greenville and Charlotte stations with a $26 CM 4221 mounted on a mast on the chimney:
