You cannot/will not go wrong with either GarGraves or Ross products. My own layout has GarGraves track and Ross switches. In large part, that selection was made because, in my local area, GarGraves track sections of all types are readily available and at reasonable cost. I chose Ross switches because of the wide variety available, and also based on recommendations made by other hobbyists I know and trust. Some years ago, I used Atlas track products exclusively, and had no problems with that line, but in more recent times, and based on where I live now, both the Ross and GarGraves products were more readily available.
The all-tinplate layout I plan to construct somewhat adjacent to my O gauge layout will be equipped with Lionel FasTrack since I have a ton of it available, including a number of switches, most of which will not be needed due to space limitations. FasTrack with "fit" well with an all-tinplate pike.
Note that I did not mention cost considerations. I view track as more-or-less a one-time expense, and tend to not really give all that much consideration to cost, within reason. Once I have settled on a type I want to use, I stick with it. Several of the switches I now have for the new layout were very costly (double crossovers and such), but they are performing well and I am very satisfied with the flexibility they provide in terms of operations.
