Discussion is always good.

I suppose if I were to pick a favorite couple, I'd go with Ayn/Sari or Alys/Rune. PS III has a lot of couples, but out of all them, that's the one that holds the most story interest for me. I'm not a huge fan of Rhys/Maia for various reasons, but I can tolerate it easier because it leads to Sari and Sari is great.

I don't agree that Alys and Rune aren't an official couple. Even though they aren't together during the present day part of PSIV, the game dropped enough hints at a past relationship in the game to satisfy me that they count.

Alys has a lot more character than most of the other gals in the series, to me at least, which also helps.
