That's a big plus for me, but everything else about putting it is a big negative.
I'm assuming that the "portion" where "it's noticeably quieter" was when you ran a train on the flex track, rather than on the EZ track.
The plastic roadbed attached to the bottom of any roadbed track makes a pretty effective "sounding board." It amplifies the sound of the train's passing. If you elect to use roadbed track, mounted permanently, you could cut down on the noise by attaching a noise-dampening material inside the plastic roadbed shell. Foam wetherstripping tape, cork, or Styrofoam would all work. Some of the noise that's absent from flex track when it's not mounted down yet, can come back when the track is mounted. It still won't be as loud as roadbed track, but it will likely be noisier when mounted. Using caulk, or glue, rather than nails, will help keep things quieter. So will using cork, or foam, roadbed under the track. The cork/foam roadbed acts just the opposite of the plastic shell roadbed on EZ track, or Unitrack. It reduces noise, rather than amplifying it. Track nails, and hard-glued ballast can bypass the cork or foam, and pass the sound right down to the really big "sounding board," the plywood table.A sub-roadbed that won't vibrate much can help reduce noise too.
It sounds like you've had a good look at several types/brands of track. For what it's worth, my advice at this point would be to pick your favorite type of track and go forward with that one type.
Yes, you can adapt just about any brand to work with any other brand, but why bother? Using up the track you have, makes some sense, after all you did pay for it, but, in my opinion, there are enough things to do on a model railroad to keep anyone occupied, without spending time, and effort, seeing how many different types of track we can cobble together.
I really like Micro Engineering's code 55 N-scale flex track, for it's highly realistic appearance. However, I did do some of the adapting two brands of track to each other, that you're now doing. I had lots of Atlas code 80 N-scale flex track around. It looks awful, not realistic at all, but it works fine, so I used that in the hidden staging yard.
In any case, I'm just giving you my opinion. Whatever track you decide on, will automatically be the right track for you.
