Squall, Zell and Rinoa.
I usually "fall in love with" certain parties, e.g. the Locke-Edgar-Sabin-Gogo team in FF6,
and the Zidane-Vivi-Garnet-Steiner team in FF9.
It feels "clean", somehow, hard to explain.
I seem to like the most "common" characters and/or the strongest and best looking ones (graphically). :D
