Yeah my laptop of choice is 15" MB Pro mid-2015. Picked up 2 of them over the last couple of years from Apple's refurbished store and I think with OS X it really is still one of the best laptops out there. A little tip - you can use https://refurb-tracker.com/ to get alerts when they get in stock.

TBH it's the MB Pro + OS X combo that works so well. MB Pro + Windows is definitely sub-par... lot of other great laptops for that. I've never tried Linux on a MB Pro.
