Depends on my mood. Vanilla isn't my *favorite* but I do get it the most. But chocolate shakes hit the spot sometimes. Especially at In-N-Out. Mmm, nice and thick. None of that watery crap! I got a Oreo milkshake (which are usually fantastic) at Coldstones and it kinda sucked cause it was too mixed up. Not thick and creamy like it should be. Which is strange since Coldstone's have really thick ice cream.
