Of all time:
ZAC & VANESSA -
I know they're RL and everything, but I have honestly never been, nor will I ever be, as invested in a couple the way I am with these two. Since before they were official, when they became publicly official thanks to those Hawaii pictures, without them saying they were official and instead getting called out by an eight-year-old girl, to many years after becoming official, I have loved and followed these two since day one; they have been through thick and thin and those that ship them have been lucky enough to witness even a fraction of their wonderful journey together. 
There aren't many couples, especially in Hollywood, who begin dating at ages 15 and 17 and are still together when they're into their early 20s. They've shared many "firsts" with one another as well. Travelling all over the world, vacationing together, supporting causes, it goes on and on. The beautiful irony of their story is that they could have met an entire year before they actually did, when Zac was at the premiere of her 'Thunderbirds' movie in LA in 2004. Luckily fate stepped in in the summer of the next year, and it ended up "most definitely" being love at first sight. As their director Kenny Ortega once said, "It really is a bit of a fairytale."
Ron & Hermione - I've loved these two since before I knew what shipping even meant; I'm so glad they got their happy ending - one of few of my couples who did. :in_love:
Troy & Gabriella - They captured my heart the moment I saw a preview for the first HSM back in early 2006, and they only continue making me love them more as time goes on.
Scott & Tessa - I don't know where to start where these two are concerned. Skating together since nine and seven years old, literally been through EVERYTHING together. When she was injured and underwent surgery, he trained with a sandbag and hockey stick. "When you've got the best partner in the world you can't just throw some random girl in there."
They have so much respect and admiration for one another, and it shines through every time whether it's on or off the ice. They really were "born for each other."
Jason & Nicky - so much angst, so much intensity, they say so much with so little!
Tommy & Jude - as much as I despise the series finale, I still maintain that if the show hadn't gotten cancelled so abruptly, she would have returned from London and sometime into the future accepted his proposal and they would have gotten the happy ending they well deserved.
