We compare them however we want. If we want a battery that will maintain 3.6v/cell at 60A continuous and 3.4v/cell at 150A bursts, we just look through graphs to find the packs that meet or exceed those criteria.

Or, instead of poring through graphs, have the label say something like "will maintain X v/cell at Y A continuous with a Z*F temperature rise over ambient". Maybe include a similar line for burst (and state how long the burst is and how often it is repeated).

Either way, C rating alone is useless without other parameters. A company could claim 50C, but neglect to mention that is for 1 micro-second at 3.0v/cell with a cell temp of 200*F. Whereas another company could claim 20C but it's rated for continuous duty at 3.6v/cell with a cell temp of 100*F. You'd probably go for the 50C cell based on C rate alone, but after reading the rest, the 20C cell is obviously much better.
