Has to be When We Were Beautiful. That's literally the only song I'd rate higher than 6/10 across the last two albums, with the possible exceptions of Amen or the Fighter.

That's not to say the rest is bad, but there's a metric tonne of wasted potential, especially with the more upbeat material. Both the Circle and What About Now are full of great songs smothered by production, in their own ways. Have a garage band play That's What the Water Made Me and it'd be a classic.
