The Howa is a very solid rifle and well worth the money. I don't have any experience with their latest triggers but have made others acceptable. The Timney is outstanding, but the cost of your rifle just went up considerably. Howa actions aren't exactly lightweight either.
Both the Savage Axis and the Tikka T3 are very good right out of the box and the Savage can be had for much less. Both the Tikka and Axis have recoil lugs built into the stock. Aftermarket stocks are somewhat limited.
I agree with PawPaw, you can't go wrong with the .308
