/tmp (of course) resides on your / partition. The problem was that people frequently ran out of space in /tmp, since tmpfs defaults to half the size of your (physical) RAM. This makes it a bad default setting. Since tmpfs uses virtual memory, it also uses swap space for its storage if necessary, therefore using tmpfs can be a good idea if configured properly. I have no strong opinions about this, and since arch is all about choice, you can use whatever you think fits best.
