I use White Lightning Epic, and I think it's brilliant as long as you are happy reapplying every now and then. This is on my Road/CX bike so gets ridden for a lot of miles, and I probably like to re-lube every 200 miles or so, maybe more frequently if it's dirty or wet rides. Definitely recommended.
I've also got some pedros stuff which I put on my fixie commuter bike. I basically lube it every 6 months (only do 15 miles a week on it) and its fine but fucking hell is it messy, black shit everywhere. Thinking about putting Epic on that bike so I don't have to deal with grease marks everywhere.
Another thing to note is how you apply the lube. If I'm not doing a full degrease, then I wipe the chain with a WD-40 soaked rag, and then slowly apply one droplet to each pin so it floods the bushing section. Then once I've done the whole chain, I spin the cranks a run through the gears. Then wipe off excess lube from the outside of the chain. This works wonders with the Epic lube - smooth, quiet, clean chain.
Apparently candle wax is the ultimate chain lube though.
