Well I've never heard of any of those three, so I can't compare them. Are they American? I rarely find American humour funny, and as a result don't really know the names of most of the USA comedians.
But if you actually listen to Russell's comedy, it is very clever. I don't think "blithering idiots" would understand some of the vocabulary involved for a start.
Comedy? You mean his poor;y received stand up that basically revolves around his "Shagger of the Year" award he received from The Sun and little else of substance.
I applaud him for overcoming his substance abuse as that is something to genuinely admire, but there's nothing else about him.
