I've used cool power 30% mostly for about a year now. Get the synthetic and it won't brown up your muffler. If your just doing hovering and forward flight the 15% is fine, you'll get a bit more power from the 30%, you'll just have to richen your needle a bit.
As for why, that's the best my hobby store carries, sometimes they are out and I'll have to use wildcat, which runs fine also.

I use the wildcat 30% or cool power 30%, my lhs carries both which is why I will use one of the two. The wildcat seemed to smoke a bit less than the cool power. I haven't made any brand loyalty because I haven't been into nitro helis for more than 2 months. Both of them seemed to run pretty good to me, the store owner tells me he sells more of the wildcat than cool power but I don't think that means much.

I actually use a mixture of coolpower 15% and 30%. I don't do 3D but want more power than 15% so for me it's a good compromise. Basically it's 22.5%.
