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.
