Sorry, didn't mean to make it sound like I use all three, I just use Whirlfloc. You of course can use the one of your choosing. As for which is best I've only ever used Whirlfloc so far so can't comment on whether it's better or worse than the others.
I had some fairly poor results using MO and hops only, fairly cloudy beer but my last beer also had some crystal malt in to darken it up and it came out very bright. However, that said, the last brew is the first one I have refrigerated after it had fermented prior to kegging so it's more likely this was why than any peculiar success I had with the Whirlfloc. I've only done 5 AG's in total so far so it's all still a big learning curve for me too but I've yet to make a bad one.
