If you're looking for the absolute best products I agree with @chopedogg88 (who gets me my AVPro Edge stuff) and @GregCAMS. They are really the best around and have a lot to offer. For best quality with least amount of headaches, I would go with the AV over IP MXNet lineup. If 1G, use EV2.
If you want the absolute best image quality with the least amount of delay, go with the 10G. 10G is built on the SDVoE standard and offers some cool features such as built in mutliview (up to 32 views I believe), gen-lock, Dante, and 1GbE alongside the video. If you do go the 10G route and want to use PoE, note that 10G PoE switches are still quite pricey and only a few are focused on AV. Netgear has essentially created and owned that market outside of first party switches.
I'm sure @GregCAMS can answer any questions about the 10G system. I have the 1G EV2 system in my home.
