I'd take my ZTR over my B for any kind of mowing except rough brush hogging. The ZTR cut is much better, it mows about twice the speed of my B, maneuverability is far better, easier to see what you're cutting because mower is out front, easy to cut under low hanging branches, leaps tall buildings with a single bound. Downside is you've got another engine to maintain, but you only use it in the summer so it's not so bad.
