This is purely anecdotal information and I can't explain it but I have both the RS 15-2507 and the CM7777. The 15-2507 is the same as the Antennacraft 10G201 which has an average gain of 30db and a noise rating of 4.0dB VHF and 3.5dB UHF. In my application the signal gain must have been more important than the noise because I got better results with the RS model. It's been up for a few years and it's still working.

I plan to put up a high VHF antenna in the next few weeks and am thinking about using a seperate preamp for it. The Wingard 8275 looks like a good choice.
