Beater:
in my opinion, for the money the CZ sxs are the better deal going. they are a bit stiff compared to the Berettas (my personal favorite) , but provide fine value in a good servicable double that you dont have to baby when hunting.
The actions of the o/u (esp the Brownings ) are too deep and chunky for a load like 28 ga. There is that sense of tradition with a fine double sxs, but always make sure the gun points where you want when you snap it up. I used to poo poo that, but after using many doubles, there are some that just come perfect for your body and others that will shoot under / over / sideways and you are always trying to compensate for the gun. Unless you want to re-structure a stock, try before buying, and find the one that feels right for you. Sometimes, a simple butt pad lengthening make sit perfect tho. i'll keep my eyes open.
