I think this comes down to the kinds of accessor methods you need created.

If you just need a few basic get/set methods, than any of these choices would be fine and I'd pick the simplest or the most popular.

However, if you are generating a lot of different kinds of methods, you may need to base the decision on the types supported by each system.

My own Class::MakeMethods supports hundreds of different method types, so if you're in the market for inside-out accessors, or accessors for array-based objects, or accessors which return closures that perform their action, or something else a bit out of the ordinary, it's worth wading through the volumnious documentation.
