Here is a good comparison review of Sakos and Tikkas:

For that price, I think I still would go with a stainless
Tikka over a blued Sako A7. From the review, the two
advantages I see are the metal feed lip mags, and the
integrated Weaver bases. I have Sakos/Tikkas, with both metal
and plastic mags. Neither have given me issues with reliable
feeding, so that is more of a mental issue for the buyer than
a real practical mechanical issue, IMHO. As for the
integrated Weaver bases, I have no issues with the Sako/Tikka
dovetail mounting, and although you probably can't go to
"Jack's Gun Shop" and buy rings, they are readily available
from a number of web vendors. The dovetail system is rock
solid, and insures good scope to bore alignment. Now if that
was a stainless A7, I would break my arm digging out the
wallet.
From my experience, accuracy will be a wash between the two.
The Sako does come with a 1 MOA guarantee, but I have yet
to shoot a Tikka that didn't end up there after load
development, or sorting through a few factory ammo offerings.
