There are quite a few on here that have used them and will report that they are not the best. Seems that Zippy's are getting the bang for the buck right now. Best would be anything made with Enerland cells.
Losi 8T 1.0, Savage Flux - XL style, LST XXL, Muggy, 3.3 E-Revo Conversion and sitting outside 425hp, 831 Tq Dodge Ram Turbo Diesel. It SMOKES
I used a TrueRC 4s 8000mah pack for about a year, and it ran great for me the whole time. It doesn't give you as much bang for the buck anymore though since the prices are higher. Zippy's will be better for that.
I had 2 2s 8000 true rc lipos for a brushless e-maxx. The guy I sold it to still uses them and hasnt bought another battery b/c it lasts so long. It doesnt have the punch or power of the enerland 6000 25c lipos that I have but were more punchy than the elite 4800 25c and the protech 4000 20c lipos. The elites will take a little more punishment though
A friend just bought the spc 2s 8000s for his slash. When he gets them I am going to try them out in the e-revo and see how they compare. I have heard good things about them
I've been running their 5000s and 8000s and have been pretty happy with both. Havent had one cell go bad yet and I own about about 8 of their packs. I just ordered an SPC 8000 pack and hopefully will be able to compare pretty soon. I dont have any high end batts to compare though but my truerc packs hold their voltage pretty well compared to some of the other packs I've owned.
I might try the zippy's next, but I've read about some of them going bad and since they are in china its kind of hard to get any warranty support.
