I've always gotten by with a wonderbar. Granted, I sharpen the pry end some. I've used and abused them, once gutted an entire barn with one coupled with a hammer and a whole lot of New England stubborn. I now tend to use the generic ones, about half the price, so I can get two.
Something else I like is the Stanley FUBAR, both the large and small models. A decent multi-use tool, really suited for demo work but I can see how it can be used in an 'aftermath" situation also.
