Ross switches with Ross track or Ross switches with GarGraves track. Ross track is more exacting when it comes to sectional track specs whereas there can be variances with GarGraves, especially with curves. All that really means is you have to be a little more careful when installing GarGraves. You won’t find better switches than those from Ross. And they’re both made in the USA, so there are fewer chances for shortages. GarGraves flex is arguably the easiest to bend and a lot of folks use it instead of section straight tracks.
Atlas is also good, but at times in short supply. They’ve also had past problems with their switches, but they made changes and I haven’t heard complaints lately. It also tends to be expensive.
If you want track with roadbed, like RealTrax, then a better bet is FasTrack.
