Probably team 1. Though Pain is overall slightly more powerful than the rest, I think Konan gimps the team a tad at the same time. Itachi or Kisame could hold off Pain long enough for Kisame and especially Itachi to finish off Konan, especially if they are in character. Konan won't use her special jutsu which is probably her only shot at beating either of them. After her defeat, the powerful duo proceed to defeat Pain together.
