Take a very close comparative look at the tips of the points of Ross and GG switches. The GG points have an abrupt edge on them. The Ross are finely feathered to the stock rail and the top of the edge is rounded over for an absolute gentle transition. Exactly like real trains.
If you are a "That's good enough" modeler, or a "That will do" builder then GG will be fine.
IME, wired properly the MTH Real Trax is OK, The MTH Scale Trax switches have been a small tad problematic. Atlas switches...…well…….before I spent that kind of money on Atlas I would definitely go to Ross. Definitely never the 3 rail Atlas 7.5! And never again in any lifetime would I use an Atlas switch motor.
I happen to favor the Tortoise switch machine. They were actually recommended to me when I called Atlas to comment on their switch motors.
A discerning friend who is deeply invested in Lionel is now going all Ross.
Think about it, there must be a very strong reason that Ross is the most favored turnout by many folks. I respect those with budget concerns but I encourage you to check around model train swap meets. Ross can turn up in over purchases or even estate sales. IMO, a used Ross is better than any new anything else.
