Dixie Chopper Zee 2 42" vs Gravely ZT X 42"

I've been looking at these two ZT mowers and am looking for any feedback that you guys can provide.

Major highlights I can think of:

DC has a B&S Cyclonic, Gravely has a Kohler 7000.

Tire size is wider on the DC
Spindles are bigger on Gravely.

Both are priced about the same, with the DC being a few hundred more.

Thanks in advance!
