I've had very good results using Fastrack for our floor layouts. The connects have always been solid and I can usually run a fairly large layout with just a single power drop.
It does seem like some of the recent production runs of FT have had some electrical issues but most of my inventory is a few years old.
The FT switches are tough to beat for smooth operation and reliability.
The biggest drawback to FT is the rigid nature of it and how "geometric" it is compared to hand laid track that usually has more soft, gradual, organic curves. As wider radius sections become available, this shouldn't be as much of an issue.
I'm planning on building a fully scenic'd, hi-rail layout with FT in the coming year. Really want to see how realistic it can look.
