I don’t know the Old Town product, but have paddled the Journey relatively regularly. I am 6’, 215#, and size 11 shoes. Some thoughts:
I looked up the Old Town and was surprised to see it wasn’t listed on the Old Town web site, nor could much info be found online about it. To me, this is not a good sign. Very old? Not popular? I did find one place that talked about a 14’9" version , and said it was some 29 inches wide. That is a big boat and more recreation kayak width than touring kayak. One picture I saw showed a high seat back, which would make a skirt difficult to use.
The Jackson likely would do fine for you. My legs go to sleep if I as in a 13.5 version, but I find the 14 to be comfortable. Being a recent model and from white water heritage, the seats are very adjustable, which means can be made very comfortable.
If you really will be going into class II white water, then the Jackson would be the best of the bunch, but still not great. Using any day touring kayak in class II takes some skills.
