I can't imagine making this decision based on the theoretical pro and cons of stereo vs. bridged alone. If I was buying amps for a touring system maybe... but this?
If your hearing is as sensitive as you say it is you should 100% listen for yourself. I personally could not listen to one of those brands for more than 5 minutes, and bridge vs. stereo won't have anything to do with it.
My suggestion is if you love the Moon's you have stick with them until you actually hear something you like better and ignore everyone elses opinion.
