Neither. The issue they both have is they don't disclose who the actual cell manufacturer is. Xtar says made in China on their cells which doesn't make me giddy, not because it's from China but because they don't say who in China made it. Without knowing the actual cell manufacturer I am hesitant to make a recommendation to buy replacements from the manufacturers themselves.
In the US I tend to recommend that people go to a company like LiIon Wholesale as they disclose who the manufacturers are and the prices are quite reasonable to get branded Samsung/Sanyo/LG type cells. The one nifty thing as mentioned above with Orcatorch is they are not coming with USB recharge in the top of the cells which is nice if you only have one battery to recharge, but with a myriad of high quality chargers like Nitecore out there that are USB powered I find carrying one of them that actually gives me useful information about voltage and resistance on the cells to be worth the bulk of carrying when traveling, especially if you have to charge multiple batteries at a time.
