The Hanning Elektro-Werke pumps are good, they got all the bugs worked out. It is was original Italian pumps that were junk however, they are very noisy and loudly gargle at the end of drain. They vibrate and are very poorly balanced causing anything its mounted to rattle and vibrate. Garment fibers / lint would get wrapped up around the impellers and bog down the motor. They frequently leaked with time due to the weak shaft seal. If anything hard got caught in the pump the impeller would just break. I can think of a dozen other pumps that are much better designed and much better suited for a washing machine.
I know you've used some of these, they are great for the cost and personally what I would recommend if looking for an electric drain pump:
