I hope for your sake that Atlas has finally got their turnout availability problem solved. They really dragged their feet on this issue, and no matter what their excuse, I have a hard time believing any schedule they might post.
Then there's the price. I was OK paying outrageous amounts for a small 10 X 12' layout, but I'd be broke by now using Atlas on my current layout. When a 3' section of Atlas costs twice that of a comparable GG piece it made me choose the later.
As mentioned elsewhere, if you plan on super elevating your curves, pick a roadbed that has little give. WS foam will cause curves to "kink' at each sections end, as the tracks tendency is to lie flat. Cork is the better bet in this circumstance.
I bypassed the Atlas screws because it was cheaper and more discreet using appropriate flat head Robertson screws. I countersunk the ties on the Atlas just as I'm currently doing with GG. Nothing looks as hokie as a super realistic track that shows off a uniform pattern of round head fasteners. Removal altogether after ballasting should help keep noise to a minimum.
I soldered feeders directly to rails but didn't see the need to solder each joiner.
