I got into Bionicle online, actually, in '07, though I didn't actually own a set until mid 2008 (I now have plenty, don't worry).
I don't own a single G2 set. If I had more money to throw around, maybe, but I just didn't care enough about the characters to want to buy them (not at all helped by the fact that Lego where I live is like twice the recommended retail price the sets are in America, at least at these smaller price points.) I don't buy because "looks cool" but because "I can have a figure of X sitting on my shelf and I liked them in Y" - I'm that guy who helps Mahri Matoro sales even though the build isn't great.
I did follow the G2 story loosely, but it never really engaged me. There were aspects I liked about it, mostly aesthetically, but it kind of came and went as quickly as I was expecting. During it's run, my position toward it could be best described as "open, but not optimistic or interested".
G1, on the other hand, I'm absolutely nutty about and know some facts that are pretty crazy obscure, even within the fandom. Even generally known obscure information I have a very quick retention for (probably because I was the sort of child who would happily spend entire days browsing BS01... before I was ten, from memory. )
tl;dr: Not an "01'er" by any means, but solidly in the G1 camp (though I can happily entertain G2 discussion and can recognize the places where it did go right.)
