If you like limited settings, feel free to answer any or all of these follow-ups:
Does it matter whether the restrictions stem from DM fiat (“I just don’t like sorcerers”), from setting themes (“The gods have abandoned Athas, so no divine PCs”), or from print origin (“Nothing from the Essentials books”)?
If you like strongly thematic settings, is such a setting any less acceptable if your favorite races or classes aren’t part of the theme?
What about strongly thematic settings that naturally foster a kitchen sink attitude, like Planescape?
It doesn't matter to me why the DM limits the setting. If the DM limits, I obey the limits. When I am the DM, I set limits for one of two reasons; either I am using my campaign setting, which has restrictions for flavor reasons, or I'm using a published setting and follow the restrictions listed therein.
I've never played in or seen a setting that I thought was "too restrictive". I've run in all-human campaigns, when that suited the 'story' the DM was laying out.
Since I dislike Planescape (partly because of the "everything goes" nature of the setting), I guess I would say I have a natural preference for limited settings.
