Paul,

ConvexHullShrinkWrap will make a convex mesh, which is almost never a
good representation of a point cloud. That is, it totally ignores any
points that are "inside" the bounds of any other set of points. It's
easy enough to run - give it a try and see what you think on your
data. If it works, great, and it is much easier than building an
external package like Poisson Reconstruction.
