Although I do almost all CP now, I only did HP for the first 5 or 6 years that I soaped. It is fun to have finished soap at the end of the project, and also nice to be able to use FOs that are too naughty for CP.
But I really like not having to babysit the soap during the cook, or deal with the heavy crock pot insert. When I do HP now, I just use a stainless pot right on the stove - not even a bain-marie.
