I think I really comes down to what you personally like. One is a break action and the other is not. Both are probably fine guns. I've hunted with the Optima before. Personally didn't like the stock but I have a Wolf 209 and love it. Inexpensive and shoots great. The omega looks like a pretty rifle and probably shoots good too. My suggestion would be to go to the store and shoulder each rifle and see which one feels good to you. I listed the links below just incase you wanted more information.
