Netgear CM1150V vs. ARRIS T25

I recently upgraded the speed of my xfinity Internet service, but I need to purchase a new cable modem to realize the full potential speed. I'm considering two modems, both of which are compatible with the xfinity network, including:

1. Netgear CM1150V
2. ARRIS T25

I'd welcome any feedback on these two devices, so I can make an informed purchasing decision. Thanks in advance.
