If they're 1 hour each they'd actually be even more than a 12 episode series. Assuming the 12 episodes were the standard 25ish minutes each. ~360 minutes vs ~300 minutes. That is, if the movies don't inexplicably have ad breaks.
edit: In addition, movies tend to have significantly higher quality animation (as well as other things), so 6 movies is likely much better for the viewer.
