I couldn't really vote with the options given, I have never used cannisters simply because I found other options just as good (maybe better)for less money, back when I couldn't afford cannisters. I will be trying a couple out on my next tank though.
As for my preferences, I never run one filter only, and usually always have a UGF and an HOB with a biowheel (emporer or penguin) so as you can see it's hard to answer your poll. I do run a few HOB's without bio-wheels, but wasn't fond of them until recently when I started into the world of planted tanks.
