Speaking as a former JD owner and now a Cub owner, I have ZERO regrets. I replaced a JD318 with a Cub 3204 a few yrs ago and the Cub has been a more reliable GT than the JD was. Money was not an issue in the decision.
I'll agree the JD is nicer looking and possible better fit and finish but where it counts, the Cub won hands down. Compared models that were as close a match to the 318 as I could find. The Cub weighed quite a bit more and it showed. I'm not a fan of vert shaft engines but that is me. Shaft drive to trans and mower, yes two small belts to drive the pto but no twists, cheap & easy to replace but never have had the need in the 4 yrs I've owned the Cub. My HD deck made the JD look wimpy. It tips the scale at 260# and that's for a 48" model. Grease fittings everywhere, got a doz on the mower itself. Even small cross shafts on the tractor have large bronze bearings. Cast iron trans/diff housing.
I could go on but won't. Like I said NO regrets on the Cub and it was lower cost the the equivalent JD.
