I've had a little experience somewhat related to your questions. Several years ago I decided to buy a JD, primarily bacause of our experience with their 455 mower tractors and several friends that farm use nothing else. When the new JD was delivered I found that it didn't have the features that I had specified (syncro shuttle). I called the dealer to come get it and he didn't get another shot to sell me anything. He was trying to take advantage of my apparent ignorance to push something off on me that he had available.
I went to the local NH dealer that day and bought a TN65 2wd with better specs for less money than the JD. After using the NH for a couple of years I was at the local MF dealer looking for a 30" dirt scoop and saw the 1455v. Bought the dirt scoop but had to come back to look at the 1455v again. I wanted the FEL and 4wd but couldn't work a trade with the NH dealer that was satisfactory. Also liked the lighter weight of the 1455v (for my use) because I need to trailer it occasionally and am not ready to upgrade my truck and trailer. The quality of your dealer is just as important as the quality of the brand you choose.
As others have said, looks like you need to cut grass around the house with something else and use the tractor for heavier chores. The utility tractors are indeed heavier and that may be a plus for you. That weight isn't always just bulk iron. Look at the difference in the 3ph linkage and you'll see that the utilities are a lot stronger built than the CUT's in general.
I would advise that you look them all over and decide which you prefer, taking the dealership into account.
Whichever you buy, a FEL should be considered strongly. If you get the FEL, get a quick-attach setup for implements and a toothbar for the bucket.
Get dual rear remotes when you purchase and top & tilt for use with the boxblade. The controls for the rear remotes should be installed where you can reach them from the seat or from the ground behind the tractor. With some models you can't reach through between the seat and wheel because of fuel tanks, etc.
