I am asking myself the same question.
I have tried both frameworks you name but can’t seem to choose.
I read that ionic team are also working closely with the angular-material team.
Does this imply that Ionic will be more inclined to function “better” with angular-material over ionic-material ?
Would be great if the Ionic team could give us a heads up as to what is coming in that respect, so we can best prepare.
Whatever the case, great job for those 3 teams (ionic, angular-material and ionic-material). All projects are great!!!
