IMO the "best" is the one that requires the least amount of futzing from you to get your job/work done. You don't want to waste time setting up X.. resolving dependencies.. making things 'work' that should 'just work'. So, whatever solves that? Personally, I've gone for the latest available release of Ubuntu where possible, although recently i've started using OS X and shelling into a linux machine to do any necessary work that requires it. I find OS X provides a decent *nix underneath and with the addition of http://brew.sh/ http://brew.sh/ - makes it a viable choice for me over a Linux set up.
