I have microspikes and lightweight crampons, but I don't bring both nor am I an expert.
My personal experience was that microspikes are most effective on very hard snow or ice that does not require kick stepping. They bite quite well into ice. I could walk up 35-40 degree fields under those circumstances quite easily. So walking over a few miles of snow on the trail over Muir Pass early in the morning was a cinch.
However, I think I would be reluctant to use them on even steeper angles simply because the elastic bands that hold them on can slip and slide around a little. I'd be worried that they might shift at a very high angle.
Also, as the snow softens the microspikes become worthless. They just don't bite deep enough into softer snow to make any difference. Crampons with toe spikes are obviously better for softer snow, and the toe spikes are much better for kicking toe steps when it is steep.
One advantage to the microspikes. I did not feel I had to take them off as often as my aluminum crampons. The light weight crampons really shouldn't be used on rock, and I found last summer a lot of alternating between snow and rock was necessary. While it is probably not great to wear the microspikes on too much rock, they are stainless steel instead of aluminum and will hold up somewhat better. They also are amazingly easy to put on and take off compared with the crampons.
