Depends on your riding style and habits. The Dyna is easier to throw around and quicker with the 96. If you just like cruising around mellow like and are more interested in comfort than performance you will probably like the Deluxe better.
That's a sweet looking Deluxe. Test ride it and if it suits you better then your Dyna do it. Value wise they are about the same and around here it seems easier to sell a softail over a dyna. It's all about want you want and how you ride.
