IMO, the nicest 3-rail is Gargraves track and Ross turnouts for realism. When I bought Ross they required some soldering for electrical continuity, plus switch motors for automation. Gargraves have a nice selection of various diameter curves. I used cork roadbed which turned out pretty nice.
But if you get a little too lazy for all that work, Lionel's FasTrack switches with Command Control take no more than 30 seconds to program with no wires needed. It might take an extra 5 minutes to unscrew the wires attaching their automatic switch that is unnecessary with Command Control.
