DCC is for folks that like to build their own trains. PS3 and Legacy is for folks that like to run trains.
I'm glad it all reduces down to something this simple. Can we also assume that those who build are tinkerers and those who run are generally not, leading to the idea that tinkerers are better served by DCC in lieu of DCS and TMCC/Legacy?
I say this because its quite clear in reality that both DCS and Legacy require occasional tinkering too. We see feedback here on the forum on a daily basis that tells us this, and just to reinforce the point, we also see negative comments about poor product quality coming from people who expect that no tinkering should ever be required.
In conclusion, maybe DCC is best for all, not just builders?
