NCE is like Mac. Easy, needs no intelligence whatsoever to use, bug fixes are announced and implemented quickly.
Digitrax is like windows. Not the most user friendly interface in the world, but has more options and is more flexible once you learn how to use it.
That's an interesting statement. What did you base it on?
If you go to Tony's website:
http://www.tonystrains.com/productcompare/dcccomparison.htm
and look at the comparison (needs a little updating, both now have duplex radio, possible other minor differences) you'll see the two are pretty evenly matched, except for some stuff very few of us will care about. Who really wants to make up a 120 or "unlimited amount" loco consist, or use all 9,999 addresses?
and how many layouts will actually use 63 or 120 throttles? Very few is my guess. Both are also within 50 bucks of each other at MSRP, and who pays that anymore?
I think these choices depend lots on what your LHS supports, what is used in your area, what your buddies or your club uses, and what you learn on. (that's probably the big one)
When I bought into DCC I went with Digitrax, because it was very prevalent in my area, and because it was half the cost of NCE at the time. That gap has been closed. I later moved and joined a club that uses NCE. Since I no longer had a home layout I began using NCE. Their user interface is easier for those of us not so computer literate, and if you don't have a computer handy, I find NCE much easier to program from the handset.
Many of our club members still have and use Digitrax at home, and looking at them I have noticed that, generally, modelers who also like to fiddle with computers, and want a computer to be part of their railroad will gravitate to Digitrax. Guys who just want to run trains will end up with one of the other systems, NCE being most prevalent among them, with a little Lenz in the mix to keep it interesting. YMMV
Things may have changed with Digitrax since I used it last, but didn't unused addresses in the system automatically purge a set amount of minutes or seconds after being idle? (no commands sent to them) My command station used to give a series of beeps when this happened. You could also command this function if memory serves. With NCE, addresses will stay in the stack until deleted, so if the operators aren't disciplined enough to purge their address after they are done, the system will just keep them until you have who knows how many in there slowing things down, just like too many open applications will slow down your computer. Then you have to shut down the command station and re-start it. This does not happen very often at our club, as we are pretty strict about operating discipline, but it can.
For Brent: Houston is a big enough market that you should be able to try before you buy. That is what I recommend anyone starting out should do, after all, it doesn't really matter what we like. You and the other decision makers in your club should do a little hands on evaluation, then get what you like
