As a MRC Wireless user I have to say that it is a fun and very easy system to use. I have had a few problems with loosing connection between throttle and loco but since getting their latest upgrades it seems to be working very well.
However, the lack of a computer interface for MRC is the biggest drawback for me. I'm also using a Digitrax Zephyr just so I can have a computer interface. I'm learning to like Digitrax a lot. It seems that each DCC system definitely has it's pros and cons and it takes some time, study and, hopefully some personal use of each to get a feel for what is best for you.

Standard has about the best price on them.
While I have no direct experience with the Prodigy Advance system myself, a couple of friends have it and like it quite a bit. It has proven to be solid and reliable.
The only possible drawback would be if you ever intend to add a computer interface to it- MRC seems to have some "interesting", and rather expensive, ideas in that area. There are ways around that, though, especially if all you'd be interested in doing is using a computer to program decoders, since you can use other brands' programming interfaces separate of the MRC system.
