That Sako 75 Grey Wolf looks like a very nice rifle and personally I would get better glass on it then the Aetec. There’s nothing wrong with the Aetec scope. I have one but I wouldn’t do it. If I had to, I would put the Aetec for one or two seasons until I could afford something else. If you have confidence in the Aetec and you would be satisfied, then I would say go for it. The end result is you have to be satisfied and not worry about what everyone has to say. Good luck..
