If EPs count, then Lana Del Rey/Paradise. It's good, and has got a few standouts, but not up to the insane standards set by Born to Die.
If they don't, then Kendrick Lamar/Good Kid, M.A.A.D. City. One of only two good rap albums this year. Thankfully, both are incredible, and this may be the most innovative and daring non-Kanye rap album I've ever heard. It's a genius combo of old-school, Dr. Dre-style gangsta rap and experimental, Dark Twisted Fantasy-era Kanye stuff.
