This post is not intended to be a "dcc is better/worse than" discussion, I have no experience with anything other than a 1990's Digitrax Bigboy system and the same era Lenz system. After 15 years away I am getting back into the hobby, I have 4 conventionally powered engines.
I had a large O scale trolley layout that ran on Digitrax, 22'x50', 190 of main line track that could handle 10 cars running at one time. I ran models with open frame motors that were built in the 30's as well as the latest in can motors. In the 10 years or so the system was up I never had any problems other than smoking decoders from time to time as they were not as robust as they seem to be now.
Wiring was not my strong suite, let's just say I used a lot of black tape. 
That said, the system just worked. To be honest, I have not poked around on other forums to see if users of dcc are experiencing comparible problems, I will do just that as part of my catching up effort. When I read about the issues folks have with dcs and Lionel's various systems here on the forum, I am wondering if I should reinvest in dcc when I am ready to upgrade.
I am guessing that the issues I see are probably people that are taking their control systems to the limits of their respective design and intended use, most people that use modern command control are not experiencing any problems.
Any comments or insight will be appreciated.
Thank you!
