Warning: I have no experience with any of these products and do not go ice climbing or maountaineering. However, I do go winter camping and one of the most frequent places we head is up a frozen river. For that, the crampons on the bottom of our snow shoes work just fine. You'll need to have fairly agressive crampons and resharpen them every so often. Having said that, on the occasions when there is bitter cold but little snow the snow shoes are overkill and something like the stabelicers or the chain traction would be usefull. I'd think that actually trying to hike on ice in the instep crampons would quickly become misery. They look more useful on something that they can dig into further than solid ice. Someone with some mountaineering experience chime in here!
