Everything can be done with ether setup. I'm a console + controller player since I grew up on controller. Tried KBM but could never get something going with it without having to do extreme amounts of rebinding(lefty problems).

Some things are easier on PC and others on controller. I'll never deny the efficacy of mouse over healing and other useful macros KBM users have an easy time using. I've always found targeting allies easier on controller since it's just up and down on D-pad.
