I'm on the repaired MacBook Pro, and it's a beauty. On this type of battery replacement, you get what they call a "top case" replacement which includes the trackpad and keyboard...so the entire top of the thing is basically brand new. I'm thrilled with that part, as there's nothing like having a brand new clean and perfectly functioning keyboard.
I had them reset me to an older operating system, so things look a little different again as I begin to set this thing up. I've replaced some of my folders and files, and I'll finish that through the day tomorrow. There are still one or two configuration things I've got to resolve as well, but I'm basically up and running again.
