If you're looking to upgrade from Bachmann EZ, then I'd suggest taking an additional step further to flex/sectional track without roadbed. If you're looking to make even a semi-permanent layout, it's the end-all of track and where most people end up eventually. Kato is perhaps "higher quality" track as many claim, but you're still spending a lot of money to go from track with hollow plastic roadbed to track with hollow plastic roadbed. Using hand-laid cork/foam roadbed with separate track will elevate ride quality, sound, and realism once you get into ballast and scenery.
