it looks like most of these should handle the same or worse than my current rig, but the reviews tell me otherwise. Since I can not ride any of the smaller brands, what are some important numbers to consider outside of the obvious: chainstay length, headtube angle, seat angle, BB height? Frame sizing affects seat tube and top tube and wheelbase too, but doesn't look like it affects the handling characteristics as much.

Maybe after I finish my last masters degree class I can make a giant spreadsheet with all of this info, but what will it tell me?
