I'd have to go with 2007. Not only is it the year I really got into Bionicle (I had gotten small sets here or there for years beforehand, but this was the year I went all out) and has some of my favorite sets of all time, including Maxilos and Spinax. Not to mention some of the best standard Inika builds in all of Bionicle (we don't talk about Hewkii) and overall just very nostalgic to me.
The only G1 set I have is from 2009 Sadly I wasn't into BIONICLE when I could've gotten the sets for prices that weren't ridiculous, and the one I have is just one I picked up while looking for Hero Factory sets like six years ago

2007 had some great sets, the barraki were amazing.
