Ok. First of all, 7801 is just an update to their 7800 line. Everything is compatible.
The reason 7800 and 7900 cassettes are more expensive is they use titanium for the largest cogs. This has no benefit to us normal people. It weighs about less but supposedly doesn't last as long. I use an Ultegra cassette and a Dura Ace chain. The DA chain is just like $3 more. SRAM chains supposedly never shift quite as nicely...or so I've heard.
IMHO, 7900 is overkill for people w/ day jobs like meShimano is just trying to keep from loosing market share from SRAM Red. AKA carbon bits, internal routing, 11-28 cassette option, weight savings. Some folks even frown on 7900 because it only allows you to drop 2 gears at a time, as opposed to 7800's 3. Or so I've heard. I llllove my 7800. Smooth as butter baby.
