If you don't mind the extra weight, I would definately go with the WH Laminated Stainless. I have one in .25-06 and I love it. The laminated stock (and weight) aids in the accuracy department and it just feels nice in my hands. Some people don't like the large palm swell in the Tikka, but it doesn't bother me.
On the other hand, if you really want a lighter rifle, then go with the T3.
