Tikka - hands down.
The Howa Ranchland with the thin 20" barrel will not feel as balanced when it has a scope on it. The Tikka with the slightly longer barrel, and slightly heavier, barrel will have a better balance with a scope on it.
Another consideration, while Howa's group ok I have never seen an out of the box Howa group as well as out of the box Tikka.
