I mow 8-12 acres, some flat, some sloped, all with trees. Started with a 10-year old bad boy 60” zero turn that I got at an auction for $2K. Upgraded first of the year to a new eXmark radius 60” that I put lugged tires on. Wasn’t happy with the cut quality plus it seemed to use a lot of gas, changed the blades to low lift, made a world of difference. Eliminated the dual stripes of uncut grass and the engine doesn’t lug down as much.
Other options I considered included a light tractor / bush hog (trees are a problem), tried an ATV pull behind mower (very difficult around trees) and a rotary cutter on my Takeuchi track loader (maneuvering around trees is difficult, tracks tear up ground, operating costs are higher).
Don‘t know what kind of slopes you are dealing with, but steeper slopes can get really dicey when damp when using a zero turn.
