By all means...Get BOTH!!!
Obviously, both of them are excellent tractors. I would weigh the pros and cons between the two designs. Gear start vs. Belt start, Solid engine mount vs. ISO mounts, Electric PTO vs. Mechanical, hydro lever location, etc. I guess I would also compare 'apples to apples' on their overall condition and what features work.
Cannot imagine that you could go terribly wrong with either of them. Save yourself a headache and heartache and get both!
