Sure it is, because it's highly subjective. I find no great "better feeling" in OS X over Linux. I use OS X right now because I wanted a few commercial applications that Linux didn't have.
Yes it is subjective, very much indeed!
If it weren't subjective then your arguments would let anyone come to the conclusion that it doesn't really matter if I'm using OSX or Windows.
But this is a personal preference that doesn't need any more explanation. It's like arguing about two games or movies in the same genre - the one might be better in all numbers. But you can't convince other people to agree with you when it comes to personal preference and "feeling".
I see your point though, its not a reason to say "OSX is something to spend 200$ more". But in a place like this, its normal that most people here have once switched from windows to OSX and don't want to turn back.
