I've used a couple of versions of their 11s cassettes on SHimano and it seems just like Ultegra vs. Dura Ace, the more spendy ones use lighter bits.
ie. in the case of the first two, it's $50 for an aluminium big cog.
FULL PIN™ technology uses eleven lightweight, stamped steel cogs held together with 123 high-strength stainless steel pins. The result: a cassette that's light, durable and equipped with SRAM's super wide 10-42t gear range that's a perfect fit for any ride. The open design similar to our X-DOME™ cassette aids in mud clearance, giving you cleaner shifting performance and longer component life.

The 1180 is weird, it's a "1180 MINI CLUSTER" which appears to be half-pinned rather than full pinned.
I would use whatever fits my bike, provides the lowest gears and is the cheapest, in that order.
