My question would be which one makes it easier to change out chokes. Unless that’s not a concern. If it’s not a concern I would trust the clamp on barrel vs the extended choke. As much as my extended chokes loosen from doves I would feel more comfortable with it on a barrel. Both would definitely give it a good look I think and I’m sure a noticeable difference. But I also favor the looks of the second one and how much smaller it is.
