We have two TF (55-59) trucks. A 57 all original and a 55 with Nova front, Jag rear, air/auto/power/cruise/electric everything. From October to April in Texas I like driving the 57. From April to October you would have to be a masochist to drive it in the heat so it's the 55's turn. In short; drive what makes you comfortable and have fun. As you can see your question has a lot of variables to consider.
