The GX feels a bit softer and less sporty than my 4Runner, I think with my XREAS suspension I'd give it an edge for on-road handling. Both our cars are running 17's with 265/70 AT's, so very similar tire setup. Mine does have a spacer lift though.
All in all, I did like the GX470 and given my 4Runner is 2WD, I may still consider selling my 4Runner to pick one up. Wouldn't mind trying a GX460 next. And also a new 4Runner, as I forgot what they drive like.
