Best COX-supplied modem for Gigablast now?

Installation in a few days, and looking at options, there is the Technicolor CGM4140COM and possibly the Arris TM3402. Maybe others?

I'm in San Diego. I'll be using it in bridge mode (no wifi or router function) as I have a Ubiquiti ER4 that I use for my router.

So, easiest (and most stable) to set to bridge mode and least issues with Gigablast speed?
