I'd have to say Trip/T'pol. Love those two. Something about their relationship just seemed right. I love Archer and T'pol's friendship the scene chosen here is one of my favorite moments with the two. But to me opposites attracted they complement each other in ways we can't explain and Trip/T'pol were opposite in many ways which complemented each other. :)

I loved Trip and T'Pol as a couple. They were really fun to watch !! Jon and T'Pol would have had a weird relation..

I think trip and t pol were a better match because they were perfect for each other and were hopelessly in love

No! Archer and T'Pol did NOT fit together at all! Trip and T'Pol were meant to be together! They complement each other. Archer just got in the way.
