As the OP clearly stated current managers of other clubs, not ex City or past managers, I think I would say Marco Silva. Like his personality and how he comes across in interviews.
As someone with a blue persuasion as far as the City of Liverpool is concerned, it's a shame Everton are such a cluster**** of a club. Both him and Benitez could have been successful there, but I think we're deprived of the chance .
