Michael is one of the best general musicians to work in this medium, and this isn't the type of compliment I like to hand out. But he's also settled, he knows what his style is and even when branching out he lets that style shine through. He's a mature musician, essentially, someone with a lot of skills that he knows when not to use.
That's just musical stuff though, he's also extremely friendly and has probably caused more LSDJ improvement in the general user population than anyone else out there. I really admire people who can write tutorials as stand-alone writings, I love helping people out but I always need to know what they're trying to do first because I don't have a good grasp on what I can teach that people want to learn.
