I just purchased a set of Elixir acoustic strings. They were very expensive - $20 CAD/$13.33USD. Apparently, they last much longer and have better tone.

Has anyone ever used these strings before (not the ones on my guitar, but the brand)?

I'm finding them easy to play - they advertise less squeaking from sliding on the strings, and that seems to be so. They don't have the brightest tone, but it has a full, rich sound, at least so far. Hopefully they will last twice as long as my usual strings.
