I have some Panasonic cells and a bunch of Trustfire cells. The Panasonics are in fact a bit better, but they are 4x the price and maybe 20% better at most. I find the price differential is not worth the extra cost. It is very easy to carry an extra TrustFire cell or two. I have yet to have a cheapie fail and have been using some for more than 5 years. The Chinese cells fron DX.com are a pretty good deal for the price.
You do not have to shell out money for the best cells to still have a pretty decent light.
