For me, the standout feature in Mavericks is the "Ram Doubler" feature (for the old fogies among us who even remember what Ram Doubler was) -- lets you get away with having less RAM.
Given that Apple now solders the RAM and charges relatively high prices for it, the memory compression is a pretty nice feature to have.
