For my situation, the Actiontec router works just fine.
I had a D-Link Gigabit router (DGL-4100), a D-Link n Access Point (DAP-2553), and a D-Link 24-port Gigabit Switch (DGS-1024D). All was good.
When I activated FiOS TV last year, to go from Double Play (Voice, 35/35 Internet) to Triple Play for just an additional $10/month, I needed the MOCA support with the Actiontec router and didn't want to do a double router, so I figured that I'd just try the Actiontec router despite all the negative press.
It works just fine, I pulled the D-Link router and substituted the Actiontec router, while still using the D-Link n Access Point and 24-port Gigabit Switch.
It works great, and I actually like the Actiontec user interface. I didn't need to worry about n wireless because I already had a great access point and my Ethernet backbone is already a Gigabit Switch so no worries there either.
And it certainly is cool having fiber right into the basement wiring closet. Every wire in the home (coax/Ethernet/telephone) is home run to the wiring closet where the FiOS ONT is located.
