I love both of them but I would go with Mortal Komat 9.
Both are really good games i have both on xbox and i will have to say that tekken is better but if you could choose another game i would recommend assassin's creed 2 or modern warfare 2 because those two games are on the top of the charts but tekken and ufc are amazing but go with tekken :D

Tekken 6
Well, Tekken 5 DR is much cheaper than Tekken 6 at the moment. In Tekken 5 DR, you start with all of the characters so if you want all of them to start with go for Tekken 5 DR. If you already have Tekken 5 for PS2, then you should get Tekken 6.
