I agree with the others saying to select what you like. I think all the track systems available today are good ones. They all have pros and cons. There is no perfect track system. One person's pro may be another person's con. Like the trash and treasure thing...
Go to your local hobby shop or train store and look at all the track they carry. If you don't have a retail store nearby, Trackwork For Toy Trains, by Peter Riddle is a pretty good book on selecting and using most of the track available today, including Pros and Cons for each. Pick the track system that you like the best and that fits your needs and go with it. If you are still uncertain, buy a loop of track you think you like and try it out. If you don't like it, lightly used track can be sold for close to what you paid for it.
If you like a system and have a problem with it someone here will have a work around for it. The folks here use every track system known to man and they all like what they are using. They have figured out how to make the track they like work reliably.
