Power = rate of energy
in SI units energy is measured in joules, power is measured in watts = joules per second.
In flashlight terms, more energy density = longer runtimes. More power density means that it can put out this energy at a faster rate e.g. it's capable of running higher powered bulbs etc.

Nick, high power density means you can use a low capacity battery at high discharge- i.e, 16340 sized to drive several quad die LED's safely, whereas a "standard" li-ion in that size can't even run one at full power without seriously decreasing cycle life. (max discharge ~1.5C for li-ion)
There are many new developments in Lithium Ion batteries in all aspects of their components. It is too early to say which will prevail in different areas. Having adequate capitalization, reliable production, effective cost, purchase contracts, public demand, distribution channels, marketed product lines, etc. etc. are likely more important than which brand has slightly better energy/power/weight densities.
Having electric vehicle contracts with major automakers or military suppliers will move one brand forward. The consumer cylindrical (i.e. AA, 18650, etc.) battery demand is a whole other set of markets that is dominated by Energizer, Duracel, Rayovac, Panasonic, Sony, Kodak, Sanyo, etc. They will decide which Li-Ion technology they want.
