I'd go with the Cat6 if that is your choice. I'd run multiple so you can decide later if you need video, computer network, or basic phone lines. In my house, each room has two wall plates. Behind each are TWO Cat5e and TWO RG6 cables back to the basement distribution area.

" In my house, each room has two wall plates. Behind each are TWO Cat5e and TWO RG6 cables back to the basement distribution area."

Do you really need or use 4 connections in each room?

In most cases you run two of each cable to each jack so that it can either be a source or a receiver, or both. For example with 2 RG-6 cables you can have that location recieve a signal (e.g., cable TV), but it can also include a device that feeds the signal to other location (e.g., it could be the source for distributing a video signal to another room).

When I had AT&T Uverse you also had the option of using Cat 5 instead of RG-6 to distribute the Uverse signal to another room. This was convenient in several cases where it was easier to run and hide a Cat 5 cable than it was to run RG-6.
