My Fritz!Box 7390 is currently connected to ADSL2+ pending activation of the new VDSL2 cabinet, so I cannot comment on experience with VDSL2 throughput. I've been running the router a couple of months and it is very reliable and retains sync better than the Cisco 877W it replaced.
On the LAN and wireless side I am extremely happy. My Cisco router's wireless didn't quite cover the house, but this one allows my iPad to connect at a rock-solid 85Mbps in a room where it previously struggled to get anything. My iMac sits at its maximum 150Mbps constantly. The router supports simultaneous dual band wireless, 5GHz allows most of my devices to avoid the noisy 2.4GHz spectrum. The Ethernet ports are all gigabit and transfers between hosts fly.
The telephony features are brilliant, I have paired my existing DECT phones which can now dial out through VoIP or via the fixed-line based on call routing rules defined in the interface. Calls to family overseas go via Skype Connect (SIP-based access to Skype, which is cheap but not free).
I'll report back on VDSL2 experiences once I'm connected and bedded-in.
