I'd say it depends - if all we're doing is firing a bunch of missiles in turns, then I'd likely prefer a faster route; simply because it might feel repetitive after a while. If, however, the fights are similar to what we've seen thus far in that there's different stuff to do as well, then I'd probably be fine fighting five full rounds straight without even noticing. Perhaps with short breaks in-between to share a few words, or with a change of scenery to offer new options...
Additional thoughts: I do like hard missions. Those are quite often the most memorable ones.
