Either rifle would be fine, and is a whole lot nicer than a lot of other entry level rifles, like the Remington 770, etc. They are both probably better guns than most American mid-grade rifles, except for cosmetics.
People dump on the A7 and Tikka because they are a bit cheesy in apprearance, and contain more plastic than the better Sakos. I am guilty of that as well, (especially the plastic bolt shroud). It does not mean they shoot any less accurately, or are less reliable though. Liken it to buying a bottom line Lexus, or BMW. Not as nice as the high end ones, but a whole lot nicer than a loaded Neon.
