I think the synthetic stock on the Vanguard S2 is head and shoulders above the other two. The trigger is also excellent. The Tikka and Vanguard come with the same accuracy guarantee. The four Vanguards in our family shoot sub-moa and it is well established that Tikka's are super accurate out of the box. I would not put the RAR in the same class as the Tikka and Vanguard, not even close. I prefer the Vanguard over the Tikka because for me they are just as accurate, have a much better stock that won't bend if you are using a sling for support, cost less and I'm recoil sensitive so Tikka's are too light.
I also cannot stand factory Tikka rings. Whenever a customer buys a Tikka and I mount the scope I suggest they purchase Warne Tikka rings, or if they are a Leupold freak I suggest the Leupold Tikka base and standard rings. Much as I hate the factory rings I've never had a customer that used them come back and tell me they failed so they must work.
