I would not build a rifle on Tikka, but I will a Savage or a Remington,, anything else in my opinion is a waste and would only consider a custom action over them!
After decades one reason I switched to using the Savage is the end results are better! I'm talking apples to apples the same price point Tikka or Sako aint beating the Savage in competition! I learned a decade ago, if I wanted to win in factory class, I had one option, buy a Savage! No other maker was or is able to produce the out of box results from a factory stock rifle on the target, that is proven!
If you want to compete in custom class, the custom actions have an advantage, but Tikka Remington, Ruger or anyone else has no advantage over using the Savage but those others will cost you more, and they still won't be a custom Batt, or Kelbly variation.
One other thing that after that made me change and that is, I want to see you change barrels and set your headspace in 5 minutes off yer tailgate with a spanner wrench and a brass machinist hammer and shoot the same hole at 100 yards.
Sorry, but I'll take ease of use, accuracy and dependability over a little smoother and imported rifle any day, and save some money doing it!! But I'm just a shooter,,,, and to me the results at the target paper or organic, is what matters the most! Probably why we don't see many Tikkas customized, or winning in competition, can't say that about savage,, in any model!
