Teflon tape or pipe dope?

I'm re-routing some 1-1/4" copper plumbing and several of the connections are threaded, including a couple of fairly beefy unions. I've pretty much always used teflon tape on threads, except for gas lines where I've used pipe dope. I've never worked on copper this big in diameter before and was wondering if there is any clear advantage to using teflon tape over pipe dope...or vice versa.
