IMO, JangBricks is the man to watch if you want objective reviews from a guy who's just looking for a good set. Eljay makes good reviews for the typical Bionicle fan. He definitely seems to use more Bionicle terms (like "Keetorange" or "Metru Red" or "Mata Green") and he cares more about what a G1 Fan would want to see in a G2 set.
So really, neither is better, content-wise. Subscribe to both, why not?
