Tikka will have a smoother bolt and possibly a more accurate barrel. At the end of the day tho, both rifles will shoot better then the shooter. Shoulder them both and pick the one you like. There is also the Savage 6.5CM Ashbury that you can consider since it sounds you want the chassis. There is also a Savage LRP 12 in 6.5cm on the buy and sell, heard the seller is flexible on price
I love my 6.5cm, super accurate. You'll be able to shoot great with either.
