For me, I'd have to say Portal 2, but this is from my own experience and yours is 100% likely to be different.
But in case you're not here for a recommendation and instead are investigating reasons why people like one game over another, here's the rundown. I don't like fighting games: it could be said that I despise fighting games. I wasn't old enough at the time to enjoy the early-90's fighter craze, most of my friends growing up would rather play Halo than Soul Calibur, and whenever I've tried to pick up one I have SUCKED, HORRIBLY at them.
I get why people enjoy them, but I can also acknowledge that I am not one of those people. The new Mortal Kombat is supposed to be a lot like the old ones, and it's all the better for it, but the problem for me is that I didn't like the old Mortal Kombats either.
Portal is a different story. I love puzzle games, and Portal is no exception. I've logged god-knows-how-many playthroughs of Portal 1, and just recently finished my first playthrough of Portal 2 and liked it, a lot. Took me 12 hours to beat it, and I have emerged fully willing to go back and replay it for god-knows-how-many times. Even without forcing one of my friends to play co-op with me, I would say without a doubt that it was worth the full price.
TLDR version: I don't much care for Mortal Kombat, but I love Portal. One vote for Portal.
