All Lipos mentioned here are 3-cell.
My bottom line is that I want to obtain my Amp/Volt/Watt target, without hooking up a truck battery. ...
-- and that's assuming that manufacturers are honest/accurate about the mAh and C ratings they give their packs -- 1,000mAh rated 20C and 2,000mAh rated 10C are going to be able to comfortably deliver the same amps, volts, watts. But, as has already been said here, some manufacturers seem to have a history of being over-optimistic.
But what's also important for most people is time/quantity, and in the above example the 2,000mAh pack will keep your model running for twice the duration of the 1,000mAh pack. So, personally, if given a choice, and if other factors such as dimensions and cost didn't rule it out, I would always go for more mAh over higher C rating
