I started with microspikes and then went to Hillsounds and then got the microspikes repaired for free by Kahtoola. I have to say that I prefer microspikes. I think they form better to my boots, and the Hillsounds shift around the toe box since they are all connected to a rigid plate. The Hillsounds are closer to crampons and as such work better when there is more / thicker snow/ice cover.
