Same,
I use a Macbook pro in the field, with bootcamp and win 7, but I prefer the Mac OS on the laptop. LR works seamlessly between win7 and Mac. I use PC win7 for all my printing and main studio processing work.
LR as far as I can tell besides the keyboard shortcuts, which I don't use much, seems to be exactly the same. And runs about the same, net LR still doesn't really work well with GPU's. At least from my experience, and needs as much ram and processor speed as possible. Unlike Photoshop CC, and Capture One with both seem well associated with GPU support.
