Ozy I have some of the kahtoola aluminum crampons. I like them.
I used to wear Salewa mountaineering crampons on goat hunts, but these Kahtoolas are lighter and easier for less technical climbing, plus no front points to trip and stumble on.
They are very light weight and they slide together when you take them off, so that they are small in the pack. Once adjusted, a single snap buckle holds them on, making them quick to put on or off.They fit into a little draw sting bag, but I often just put them on the outside of my pack under a compression strap so they are handy.
They adjust a little bit to length, but you need to be close to the right size.
The aluminum eventually dulls some on rocks, but still digs in well so I have not resharpened them, and mine are about ten years old.
Not familiar with the microspikes, but they might be better if you have less snow to deal with. They look to be more suited to mixed routes with more rock and dirt, or hard ice, but less positive if you have steep open snow to cross. I use mine on some steep snow filled gullies that would be hard to keep from sliding down the chute without the 1 inch long flatsided crampon teeth. Depends on what you need to do.
Hope that helps.
