I'm probably not the right one to give you advice on this. I don't have a spigot on my pot (and don't really see a need for one right now). I siphon the wort out with my autosyphon with a stainless steel scrubbie slipped over the end. I always use at least an ounce of whole hops in my beers. These hops and the scrubbie work together quite well to filter out hot and cold break, hop pellet residue and any other critters or whatever that may have fallen into the boil.
I would lean towards the use of the bazooka tube though I have heard of clogging problems,especially with pellet hops. Part of that problem, I believe, is the small surface area of the bazooka tube. A similar product that would overcome that problem would be this:

I have a similar one in my mash tun and I never have problems with it clogging since it has a huge surface area.
