Go for good quality 12 point mountaineering crampons and get anti ball plates whilst you are at it, as they are such a big safety improvement that we insist you have them anyway.
Currently we reckon that Petzl Vasaks are the best all round mountaineering crampons, so these would be a good choice.
For a technical crampon that is also very good for steep ice climbing, then look at the new Petzl Lynx - this is a modular design so it weighs a bit more, but it has vertically orientated front points and several different options for varying styles of climbing.
Vertical front point steep ice crampons are not so good for general mountaineering, but essential if you do lots of steep ice climbing. Good old DMM Terminators are still well regarded here - however amongst hard Scottish winter activists nowadays, Petzl Darts set up with mono points are pretty much universal.
A word of warning about super light alloy ski touring crampons like the Camp XLC models - these are great for ski tours where you carry them most of the time and only ever climb steep snow, but they are not suitable for summer alpinism or any other technical use, as they won't stand up to the abuse.
