I find both fantastic and not that far apart from each other in quality. I do love Lemonade, but it's actually only my 4th favorite Bey record if I'm being honest (B'Day, S/T and 4 >).
I use every single song on Anti, which is new for me from a Rihanna album. Lemonade has both, the strongest and 'weakest' moments of the two. So this one goes to Rih for me (for now).
