Kubota & Kioti (Daedong) both make good tractors.
For various reasons, including unsuitable applications/spec comparisions, we don't operate on our farms any Kubota farming tractors so our recent Kubota ownership experience is conifined to sub c.20hp where all have been exclusively used in lawn maintenance/garden tasks.
The Daedong DK1002 100hp we recently purchased for our farms as an initial "brand" evaluation/trial unit (as an alternative/relacement to more mainstream brands which we have become increasingly dissatisfied with) has in c.5months raked up c.400hrs hard yards of (ab)use with our emplpyee operators - no complaints & importantly no downtime/failures - check out this link if you require more details

Yes, I'll have no hesitation investing more money where my mouth is & we will be buying more Kioti/Daedongs this year - in my humble opinion, for our applications/this HP range, there's nothing that comes close to their overall value equation as a utility type tractor, combining performance & build quality in a well priced package with superior customer service.
We learnt a long time ago that commercial sense & maximising profitability of farming operations aren't contingent upon brand alliance/allegiance.
So it's interesting to see perceptions continuing like "Kioti's being a poor man's Kubota", I recall similar sentiments too when Kubota "upsized" from CUT's in our market & was perceived as the poor man's choice (in lieu of American/European brands) - oddly enough it was the likes of IH, Ford, Case, Massey Ferguson, Fiat, Allis ...etc who either became defunct or merged with other tractor brands to survive..... Look at vehicle brand volumes to see how the Koreans have rapidly increased global market share on the back of almost unbeatable value equation/volume production costs on "no-frills" products (just like the Japanese did to establish themselves in the 60's/70's) & they're doing the same with forklifts, earthmoving equipment, tractors...etc.
