Does GMRS have better range? How/why? With CBs lower freq I would think you would be more likely to occasionally at least be able to take advantage of skip , sporadic-e, atmospheric ducting or something.

GMRS is UHF (some countries have a similar service called UHF CB).

In the US you can run up to 50W legally and use repeaters. CB is limited to 4W AM/FM and 12W SSB. While 11m does offer performance beyond line of sight, CB generally suffers from poor antenna installations and excessive noise.
