One difference is that the G1100 is newer and from a different manufacturer. Main difference it has DUAL band wireless 802.11AC. The actiontec is only single band( 2.4) wireless 802.11N.
Its not clear if the MOCA 2.0 support makes that much difference at least as far as Verizon configurations are concerned.
