Well he is a pro. Attended the Conservatoire in Nice, France. So like Berkeley trained musicians he brings a rigorous approach rather then self taught Stan Lynch. Steve can write and read music which I am not sure if any of the heartbreakers can do except Benmount.
I think Steve grooves better than most drummers and can handle more styles. He brings a great groove to everything the HB’s do but his personality doesn’t come out as strongly as Stan Lynch. So Stan did a lot more to shape the sound of the HB’s, as an original member. Stan also sings great harmony like Roger Taylor or Don Henley - so he probably was a better fit.
Steve is a good friend of Mike Campbell. Stan was a buddy of Benmount. Keeping a band together is as complex as a marriage. Success often leads to a breakdown.
