but what is the difference spec wise to the Lepton3 160x120?

It's radiometric, can provide temperature-linear output.

From the datasheet you can also change the gain for higher dynamic range/lower sensitivity.

It's radiometric, can provide temperature-linear output.

So it's radiomatric, in that the pixel value is proportional to the temperature (not proportional to the voltage of the actual microbolometer array's signal). Does it also output the calibration data needed to calculate an actual temperature values (like degrees F)? Also, can a command be sent to it to get it to output a signal that is proportional to the sensor's voltage? Or for that would you need to downgrade to the 3.0 Lepton?

The pixel value is directly related to the temperature, usually some mK per count. No calibration data needed, though you can compensate for atmospheric temps and whatnot.
You can also disable radiometry and do AGC like on any other Lepton. Just look at the datasheet, it should be fairly clear.
