the 21057 is a 6.1 cooked rom thats like stock. the 6.1 stock rom build is 21052. in 6.5 the 21916 build is the most stable and reliable under 6.1 the 21057 will probly be the most stable and reliable one as its the newest and latest one (tho the 21056 blackout rom seemed buggier than the 21052 stock rom).
