I have both (two) Limited's and one TRD OR. I use the TRD OR as my daily driver about 100 miles a day. I changed out the shocks to Bilstein 5100's and changed the coil over springs on the front's - ~$1,300. I think my ride quality is very good and compares well to my Limited's.

The TRD OR is more responsive to drive due to the lighter wheels and really being a 2WD truck most of the time, where as the Limited's AWD adds more drive-train drag, especially noticeable when accelerating from a full stop. My MPG's are slightly better in the TRD OR.

You should do a test drive of both with the knowledge that upgrading the TRD's shocks and you can get equal or slightly better ride quality - the 17" wheels/tires ride smoother, the 20" wheels/tires are firmer. I can drive either for my commute and I use the TRD OR.
