Oh well... just another article in the usual amateurish TH style... The title should have been something like "What cell/charger/flashlight/CDP combo we found to be the ...".
While a grossly inconsistent, and empirical method of evaluation was used, it amounts merely to a loss of time and resources, the whole green propaganda left aside. Still no clue about the already caught red handed high priests of AGW?
If cell quality would've been the issue, then try to use at least some more scientific methods, like testing under the same conditions, using some calibrated measuring gear, proper for the task, and so on...
Hint: use a battery analyzer, which offers charge/discharge curves, at different rates, eventually at different temperatures.
Every cell chemistry offers some advantages, and disadvantages: (dis)charge rates (mainly depending on internal resistance), self discharge, ability to work under extreme temperatures, cycle life, and so on. It's all about compromises... depending mainly on the application.
A lot of pertinent information is available on the net... just do a little search.

For example, Maha products (not even a mention about them...) are highly regarded, offering high capacity/high self discharge Powerex cells, or lower capacity/low self discharge Imedion cells, and one of the better chargers around: MH-C9000.
