Without seeing your land, and specific uses, it would be hard for anyone to really do a fair assessment of your needs (not saying the dealers are wrong, and all of us here are included in this). I have 15 acres now, that might grow to 55 eventually, and it's broken out similarly to what you describe. I've got a 5,000+lb 4wd tractor (counting FEL), and a 4,200lb 2wd tractor, and they absolutely aren't overkill. I've been clearing trees, brush hogging, box blading, moving dirt, etc, and there have been many times I max the capability they have. I could easily go one or two steps bigger, and be happy. People joke that tractors shrink when you get them home, and I have to agree. Many people here report picking the perfect size, and a year later trade up a size....very common, and can be an expensive lesson.
Obviously, I'm very happy with my LS (you can actually get parts or warranty work at any NH or Case dealer, warranty requires LS approval), but almost bought a Kioti....both great machines. For the same money you'd be getting double the FEL capability (more actually), and a nice jump in PTO power that would let you run bigger implements....along with a lot more weight, which equals traction, which would be much better for ground engaging implements.
The new Massey 1635 would be very similar to the Deere and Kubotas you're considering, and the prices seem to be a reasonable amount lower....from what ive seen, the reports are positive on them.
