I very much prefer the TT. It fits me far better than the Cheetah, which feels very cramped to me, especially in the foot area. I do like the suspension platform idea, but since you are a HO and won't be mowing all day, every day, the TT with the suspension seat is more than enough, and the TT has a rock solid rep for good reason.
If it were me though, I'd be buying either one with a Vanguard BB in it. They are top of the line engines, and have excellent reps for power output per size, and durability. Don't let the B&S name fool you. The only thing that they have in common with B&S is that B&S imports them, and partnered with Diahatsu in building the plant where they are made.
