I'd choose the Ruger American over the Howa, Weatherby, or Winchester in my experience. Not sure about the Browning.
I really wanted to like the RAR best, but you can easily bend the stock with your hands, while the Winchester, Browning and Bee stocks were rigid and much stronger feeling. They all fit me better, too. I didn’t like the Howa stock all that much, but it wasn’t flimsy.
There's no doubt the RAR stock is more flexible in the forend, and benefits from some extra free float work. That flexibility doesn't seem to matter though; it's a more advanced action design that doesn't rely on a stiff stock for accuracy.
My results with the RAR Predator in 6.5 C echo what MD and TN deer hunter posted above. I recommend them based on how they shoot, not how the stock feels.
I did add a cheek piece to mine though; even with low rings the RAR stock cheek piece is too low, although the angle is right.
