In that case, the subcompact would seem to fit. A couple of things in its favor are the 100 hrs - which I tend to regard as "proven" rather than used, reasoning that's enough time for any manufacturing errors to have surfaced and for the PO to have dealt with under warranty.
The backhoe is handy for doing home landscaping work. I'm older and so is my back. So ours BH gets used more for precise craning and lifting than for digging. A BH bucket is also hard to beat for working up the top soil of a small garden....especially if rocks or terraces are part of your landscape plan. Having a thumb on the BH doubles the usefulness.
Everyone should have a small box blade. They cost very little and can be handy - though I suspect you won't use it much after the first trial. They are still good to learn on and just about indestructible. Look around for a used one.
Common box blade features to look for are adjustable depth rippers and a flip up back cutting/smoothing edge. Don't get too large a box blade for the subcompact.
However, since you will have the stronger FEL, there is an option. The FEL loader bucket held at a slight angle - always less than vertical - and dragged backwards does most of what a small box blade can do & you can see it as it works. Adding a bolt-on tooth bar to the edge of the FEL bucket imitates the rippers of the box blade & is another handy tool to have.
Try backdragging on your ruts to see if it works. If not, the box blade is the next step.
I don't know Masseys well, but so far haven't found any negatives. That model has been around for over a decade and is simple in design - both strong pluses. The Iseki engine is known for quality.
Good luck,
