Are you looking for new (newer?) or used. Personally, I like the older 40 series Deere's. Simply light years ahead of their competition from that era. (Especially the 4440) Looking real hard at a low hour 4450MFWD at the moment. I've got 3 6430 Premiums (2007 and 2008) and have nothing but praise for them Bought two Masseys in same size range and wish I wouldn't have. They just don't hold up to the hard use like the Deere's do, not to mention the rather substantial drop off in worth after a couple seasons. We demo-ed a couple NH's this fall, and crossed them off the list. Operators just didn't care for them. We demo-ed a couple Challengers too, but since they're essentially a Massey (albeit with a slightly better service contract available to us) they didn't stay on the list very long.
I've had a history with MF's and still like their older tractors (under 100hp) but have had such good luck with the Deere's, I'm beginning to see just one brand as an option. No decent CaseIH dealers in this area, so they're out of the question.
It's not uncommon for us to put as many hours on a tractor in 2 or 3 seasons as is typical of a farm tractor in 10 or 15 years, It's very critical to get a unit that has a long life expectancy. (and a good resale value once it has high hours) No one has been able to stand along side of Deere in that regard.
Adding a pair of 6170R's to the mowing fleet this coming year (140pto hp) (will be pulling 20' bat wing mowers) I'll be able to comment more on them in a few months.
