I agree that the dial model has the edge on overall accuracy. However, if I could only afford one wrench, it would be the clicker because rarely am I using it on an engine stand or bench.
Tightening up the suspension piece can be done with a simple click, or try a mirror and flashlight and a lot of strain to see that little dial gauge.
Accuracy within 4% means 8lbs at 200 ft/lbs and that's the advertised limits. Most likely it will perform about as well as the dial model.
