Yeah you've done it right. I was waiting for the results of the poll too
I guess you need an audience the size of URs to garner a good result to a poll on several different tanks. The problem is, people will usually only have had one of the above, so all they can do even if they have first hand experience of one, is either vote for the one they had, or not vote for it if they didn't like it for whatever reason. Few people will have had one of each to be able to compare.
I really like the Evolution Aqua 600. Think it looks the dog's, but not too chuffed about it being open top, but you don't seem to get "high end" looking tanks that aren't open top. (blocking light)
