Runtimes vary by discharge rates -- for example, lithium primaries have a huge advantage over alkalines in high drain devices, but roughly the same performance in low drain devices. With that said, an Energizer Lithium AA is typically rated at 3000 mAh, where Eneloop AAs are typically rated at 2100 mAh.

For myself, I use lithium primaries in devices that are infrequently used, because of their extremely low self-discharge rate and I don't have to worry about leaks. I use Eneloops or 18650s in devices that are in constant or frequent use, where the cost savings matters to me and where maintenance charges aren't an issue. I do not use alkalines.

Here is a link to the Energizer Lithium AA datasheet and the Eneloop AA datasheet.
