Eastward YJ j06 or KD C8

Hey just a quick question...I have a eastward YJ j06 (xml) I bought from dealextreme, and find the thing is great. But I've never really seen anyone talking about it, people mainly seem to like the KD C8(xml). Is the C8 that much better or is the j06 just extremely unrated..The only other light I have to compare the j06 to is the uf-2100 I got through the group buy on this site, which I really like as well, but the eastward blows it away in build quality, and output. But is a lot bigger in size so:

Does anyone on here have both lights, can give me a honest compare of the two...thanks.
