I'm a big fan of manual trans for work trucks and hot rods but not as much for lengthy commutes in heavy traffic..
my [dad's] 65 C20 and my red 71 longhorn are both 4 speeds with no plans of changing..
I will admit they can be challenging in slow traffic where gear selection is limited..
easy to drive on your own pace but not so much matching other driver's pace in stop n go traffic..
I did convert my 74 C20 4 speed to TH400 over 20 years ago when commuting to LA..
really depends on the use of the truck, which for me are all destined to join me in retirement..
then I don't plan on dealing with any traffic for any reason
