I do not own any Fastrack so I cannot comment on it. Others have said it is noisier than the SHS track. I had three loops of SHS sectional track directly on a honed limestone floor in our family room this past Christmas. I used a small piece of double sided tape under every fourth track joint just so if it is bumped it does not slide around. With three trains running there was no track noise. Original Gilbert track in rubber roadbed also works well on a limestone floor but it does not look as good nor come in a 30" radius. Also the rubber roadbed is hard to find. American Models track does not include a roadbed so I have not commented on it. The original Gilbert track switches are bullet proof and have the selective power routing feature for multi train conventional operation. Flyer Chief and Legacy do not need this feature so the SHS/MTH turnouts work well with those control systems.
For information, we selected MTH flex track for my permanent layout. I just bought 600' of it. Unfortunately (from a time and cost perspective) all the turnouts have to be hand laid.
