I'm not going to bad mouth the XJ2025, but it's a much older machine with ergonomics that match; that said they seemed pretty similar in dimensions when next to one another.
The MT225S is roughly the size of a larger frame Deere 2 series, though it may more approach a 3 in weight, I don't recall the weight of the 3033R I was looking at. The MT2, essentially, uses the same Yanmar engine as the Deere 2025R but attaches it to a 3-range transaxle. It's got a nice, open operator platform as well, with a big adjustable seat.
The MT225S is a shot across the bow to the competition, I was extremely impressed with it.
I was also quite impressed with the Kioti CS 20 line, but they were too small for my use; they improved on the CS 10 in seemingly all ways.
