I tend to agree. I use Mac OS only because it natively supports Photoshop and MS Office and I may need to install these at some point. It also has first class support for the kind of dev I do (e.g. most other devs in my field also use a Mac) making troubleshooting slightly easier. As for the UI, until Mavericks I think it was behind the last stable Gnome 2 release. Now it is ahead in some areas but still behind in others. Finally, Ubuntu continually screwing up things like audio support or ruining areas of the UI (ironically to make them more like OS X) also helped me make the switch.
