I definitely agree with your last paragraph - it's why I always recommend Tikka for a more budget rifle. IMO, it's the best value proposition in this sport. Quality action that feels and functions great, tight enough tolerances that shouldered pre-fits can be spun up for it, and amazing aftermarket support that continues to grow. They also shoot extremely well out of the box.
No matter which way you go, there's compromises. For the Tikka, it's the OEM stocks, the bolt stop can be a weak point, and the factory barrels, while great shooters, are generally on the slower side. They also used to have a gorilla that torqued the barrels on at the factory, but I think he's since retired. For the R783, it's weak aftermarket support, which would be a deal breaker for me. For Big green and Savage in general, it's poor quality with high chance of getting a "Friday gun".
There's lots of great options these days. Don't discount Howa or Bergara as well. Determine what you want in an action, and what the pro's and compromises are for each action you are considering. There's no free lunch. Thankfully with most modern manufacturing practices, most guns are pretty decent shooters out of the factory, compared to what they used to be. It's other factors, like quality, features and aftermarket support that end up becoming the bigger differentiators.
