.... The Peco seems to be about 3 inches shorter and a slightly tighter radius. Am I mistaken by saying the Peco 99 is similar to the Atlas #4 radius? .....

You are right. The Peco looks similar to an Atlas #4.

This Atlas #6 replaced the Peco 3-way on my layout for the price of one stub track......

The Peco 3-way switch makes some funny and irritating noise when trains roll over them but it is only an irritating noise. I had never any derails. It operates rock solid.

You should try the longer Walthers if you can afford the space. I looks much better.
