If looking at 65+ then ALL ford smallish tractors are gonna be 3 cyl
ie.. 2/3/4 series. by the time you get tot he 5series.. you are getting into a 70hp machine. 
prior models.. liek the 6xx/8xx are obviously older. many people overlook those and find the 3 cyl instead.
Did I actually say that the 3 cyl are more troublesome? or did I refer to something more specific? for instance.. on a gasser 3 cyl.. the carbs are more finicky if a holley.. and the puel pump system is a bit drawn out.. etc.
the basic mechanical pto setups from the 3000 and down are 'essentially' the same technology. a very minor difference in some parts and R&R.. etc.
drivetrain is also similar.. again.. untill you get to 4000.. then you get gear reduction and wet brakes.. etc.. etc. independent pto.. different pump setups.. etc.
kinda really depends on the subsystem in question as to what is more difficult.
the front axle and bolster setup from 39 on up for any of the 3xxx ag series that use radius rods is virtually identical in function and repair, if having a few parts and setup differences.
hyds changes at 65 and 75, and between 3xxx and 4xxx models.. etc..
sheet metal differences.. etc.
wireing is for sure more simple on a pre 65 model.
if you have a specific question, shoot. otherwise.. we need to talk about a specific system if you want specific answers.
for instance. I'd rather rebuild the pto on a non independent pto machine.. or do the brakes on a non wet brake machine.. just due to less steps and disassembly.. etc.
