My experience with EZ track is just from some that I used for a temporary test loop and a small 3'x3' layout I built for my son. The track itself works fine once you weed out the bad sections. I had close to a 20% reject rate when building my son's layout. Using the 11" radius corners about 1 in 5 will be undergauge. For running diesels, this is usually not a problem but my 3 year old is a steamhead like me and steam loco's need great track to run smooth.
The turnouts are pretty reliable but need some filing of the points. They are also nice because they are power routing. Once installed on his layout I have had no problems but they did take some fine tuning before that point.
The EZ track can be used with sucess but plan on trashing some track in the process. Get yourself an NMRA track gauge or the one available from MicroTrains works well and check every piece of track. Test and retest with every loco you have before finally mounting the track. Any track that is questionable, throw away and replace it.
My layout is being built with flex track, my current test loop is now Kato Unitrak.
