I've never SHOT a Caribow but in a straight up trade you probably have more value in the Caribow in case you would ever want to resell it. The Caribow will most likely be more polished and finished. It's been my experience that Jim's bows, while very well made, tend to lean towards the more plain side. A great no nonsense hunting bow. I would also think the extra 2" AMO is better for your draw length.
Having said that, I currently own a TS Mag, love the grip, so I personally would pick the Mag.
