Not tried toughdog suspension, currently using a 2nd hand set of OMEs. They're a bit hard but no doubt I don't have enough weight in the car for to spring rate.
Have used toughdog rtc steering damper and quite liked it until I managed to bend it. Now using their adjustable jobbie...... Jury is still out on that one though but I do like being able to stiffen up the steering for road use.
