The advantages of the Ruger are that it is a unified chassis instead of a traditional action+stock which doesn't require any kind of bedding for accuracy, it takes cheap detachable mags in pretty much any capacity you want, it has a fully adjustable stock where every dimension can be adjusted to fit the shooter AND can be folded for compact transportation/storage, it has a good trigger out of the box, it has a 20 MOA picatinny scope mount out of the box, it comes with QD flush cup sling sockets out of the box, it has a free floated Keymod railed handguard that makes it easy to attach any accessory you want... basically it came with everything I wanted right out of the box, that I would have had to spend hundreds (if not thousands) more on any other rifle to have.
I don't know how accurate a Tikka or whatever is, but I don't see ever needing to hit anything smaller than 1/2 MOA, so I guess I'm good with the Ruger's accuracy. It's kind of cool that the Ruger can do it with off-the-shelf ammo too.
