My favorite by far is the 188A.  I really like the size and design of the black tennite handle and the indexed bit storage in the handle.  It’s got a really tight action.  They’re fairly common and affordable too.  There is also the 185A which I don’t have but it has a solid steel body and handle with knurling on the handle.  It was a carryover from the Goodell Pratt line after the acquisition.  A lot of people kinda hold that one up as the gold standard.  I don’t think there’s any difference between GP branded versions and MF branded ones.
