You really need to go to a range and try them out, if possible, or at least a gun shop near you and handle them. Anyone on here is going to recommend the same thing. We don't know your hand size, we don't know how you shoot, if you shoot/have any background in shooting. We don't know your frame size ( of your body ) - if you are wanting to carry or just use it for home defense and plinking. There are far too many variables for something like this. You need to go and handle them, then ask questions about what YOU noticed with each model.
Of the two choices, if I had to choose one, I would choose the Walther, but neither of them are what I would consider a great weapon.
