Deere 310C Large Metric or SAE socket set ?

I have a Deere 310C Likely 1989 vintage... I also have a good collection of sockets in 1/2 inch drive. :notworthy


For the larger sizes, I'm looking at 3/4 drive. Which socket set will have more use on the 310C ... Metric or SAE?

Or should I go to 1" drive sizes ...
