I use Anyrail, it is easy to use and the only real problem is when it updates your old track plans won't be able to be viewed in 3D mode. Other than that you can add your own textures for grass, water, mountains or such to make things look more vibrant than the typical color choices you are given.
There are user created objects as well(and you can also create too), and the Oscale side seems light compared to the other scales. I had contacted them about creating more Oscale options for turntables(as the only have Atlas 24") and their reply was that they didn't have exact numbers for the other turntables I asked them to add(MRS & Ross).
