I think the OP is asking for a comparison of the two, not the pros/cons of both...
It's probably going to come down to whether you have a strong preference for 16x19 (4D300) vs 18x20 (4D300 Tour). When I tried both shortly after they were released, I actually liked the way the Tour model swung better. The non-Tour feel was more to my liking though, and since I prefer more open string patterns, I went with the non-Tour.
