The Tikka is made in the Sako factory and Sako was bought by Beretta awhile back.
To my knowledge, the Tikka rifles are not marked with either the Beretta or Sako names.
Dunno what the price differential is, but I've heard pretty good things about Tikka, and of course Sako is generally considered top-notch.
If the prices are comparable, I'd take the Tikka.
