I like the click style.
The bending flex type are often difficult to read accurately because of the distance between the pointer and the scale. If my line of sight is just a little bit off of looking directly at the scale, my reading will be wrong.
As for really low torque values (like the filter cover and oil pump inlet screen cover bolts need), a small 1/4" drive click torque wrench is available and it's quite accurate (even for the cheap ones at Harbor Freight).
For just a few dollars a adapter can be bought that will allow the little 1/4" drive wrenches to drive a 3/8" drive socket.
That's handy if most of your sockets are like mine, 3/8" drive.
