Default Johnson vs. Ranco controllers

Maybe a stupid question, but I have a couple of each and it seems like the Johnson controllers constantly under-shoot temps by a degree or two when used for fermentation purposes.

For example, for I'll set the Johnson at 61F and it keeps running all the way down to 59F occasionally despite setting the differential at 1 degree. The Ranco actually seems to cut off when it's supposed to.

Is it just a bad controller or am I just doing something wrong?
