It's all perspective...
Previous to the xD, I had a VW Golf. The ride quality was a great mix of sporty and comfortable. The xD, in my opinion, didn't do either of those well. I bought the car with the TRD struts and springs. Too rough for me. I commute about 70 miles a day, and it was harsh... even on the realatively smooth roads around here. I would hate to have driven it in Detroit or between LA and Vegas. I dumped the TRD setup for the stock struts and springs, and was happier... but it wasn't particularly smooth or sporty... somewhere in the middle, but not in a good place like the Golf.
Now I drive a Subaru Outback, which has about a mile of wheel travel, and fender gap that would give some of you guys a heart attack! However, Subaru seems to be better at stock suspensions than Scion/Toyota. More like the Golf, it is relatively nimble, and also smooth on the highway. It takes speed bumps like a champ! It ain't no Cadillac, but I'm not into the "floaty" ride.
Again, just my opinion. Some on here will say that their car is 1/2" off the ground and has 1/4" of wheel travel and rides smooth.
