Gidday Kyle, I use Peco Code 100 Nickel Silver Flex track mainly because it’s been historically available here “Down Under”
BUT going on your first post regarding about “Fold down layouts”, you mention moving because your Dads in the military. Now while I don’t know which of the good advise you’re tending towards, I would suspect that whatever you build will be Small, Simple and Robust so perhaps EZ track might be your best bet at this stage especially as you already have some.
Which brings me to my second point, Budget. Now I think I would be pretty safe in saying that very few of us on this forum have unlimited model railroading funds, but making the assumption that you’re a young chap obtaining funds maybe harder. What I’d suggest that you work out your track plan and what track and turnouts you require too make it happen, then shop around.
By the way when I said “Simple”, I am NOT suggesting that your layout would be stupid.
