Hey there newcomer!!! Please, sit, make yourself comfortable. ^_^
#! is indeed a great distro, and it's nice to hear that you're enjoying it so much!!
There are many great things about Linux, but some don't often get mentioned. So here goes my own observations!!
Firstly, there's none of this "My computer is faster and thus better than yours!!" here in #!. It seems we're more like artists, who work with what we have to make nice and functional machines, that are a pleasure to use. We don't flex our e-peen's very often. XD
Secondly, we don't generally mind if you stretch your legs a little when it comes to Linux. You said this is your first distro. I wonder what made you choose #! to start with. To be honest, it's not the most user-friendly, if you want to adjust something yourself, generally, you've got to open up a text file somewhere and change a setting or adjust a figure.
My point is, no one will take offense if you want to see what the other distros are like. If you tell us you've run a LiveCD of Knoppix (or whatever), let us know what you think!! We won't be mad if you install a new OS, or you find this to not be your liking, or it takes you a while to get used to it. Really!! It's all good in da hood!! XD
Then there's the support you get. Of course, Linux is free, and thus they don't really offer lots of "technical support" on demand, like if you went to an Apple store and spoke to a sales assistant about your machine. You can't really do that with Linux.
But what we have instead is "community support", awesome forums with awesome people, like the person above here!! We (mostly THEY) help out other people with their issues because they enjoy doing it. They are good people, who like to spread their knowledge and make the world a slightly better place.
Those who do something because they enjoy it are generally going to do better than someone who doesn't want to be there, right?
These guys always try their best to help you out, no matter how "noobish" your question is, or how seemingly obvious to us the answer is. We're friends here, not just bounded by the coincidence of running the same software on our machine, but we've got things in common!! The same people who use #! to design, make it look nice, make it work, find the flaws and patch them up!!
All the mentioned above, and so much more is the essence of Linux!! There's so much to this OS, and even more to the people and the way it's made and all the effort behind it.
When you buy a Mac, you're buying a way of life. It's the same with Linux, but a very different world-view. I'm sure you'll get the gist of it.
Again, welcome to the community, friend. I am goin' to enjoy your being here!!!
Also, sorry for typing loads, it's a problem of mine. 
If I make people laugh, that makes me pleasant, right?
What if I make people laugh about unpleasant things?
