At first glance, I thought black was clearly better, but once I try concrete ideas, I end up with nothing to show for it.
I think the root of the problem is that the black rook looks superficially well-posted, but it's not. It's really locked into a pseudo-defensive/passive position where it leaves a weakness behind whenever it moves. If it had the ability to move to the g- or h-file (behind the white pawns after they have advanced) and create some active threats, it would be much better, but that's easier said than done.
I've been trying ideas where black lets the white kingside pawns run, holds them with the king, and then slides the rook to the kingside behind the advanced white pawns to attempt to alternate threats against the pawns and also the white king, but white gets to move as well, and I have nothing foolproof yet.
