I own many brands of rifles, including the Remingtons and Tikkas. IMHO the Tikka has better quality and perhaps better accuracy (although virtually all of my Remingtons are MOA or better as well).
True, the Sako is a better gun than the Tikka, and that's in part because the Sako does not use plastic parts like Tikka does. The barrels are the exact same too. Still, at almost double the money, although Sakos are nicer than the Tikkas, I can't say that they are twice nicer.
The Tikkas really are the best value on the current market.
