this is true. but some other people in this thread trying to use it as the poll to end all polls have the wrong idea (not directed at the poster above me). for a poll to apply it needs to be perfect. data skews FAST.
The best thing I could find was this.
http://www.googlebattle.com/?domain=Lucario&domain2=Mewtwo&submit=Go!
which has lucario having more overall internet relevance than mewtwo despite a third of the lifespan... it's also very flawed but covers more audiences and is just as usable if not moreso.
the only other poll I've heard of was one in japan that had polled the public and had pikachu, jiggly, and lucario in that order as top 3. but that was before gen5
