Most people if not everyone I have discussed this with consider continuing to a landing the better option assuming a normal approach from the automatics.( Various UK jet operators)
Flying a single crew go-around and diversion is not something I would consider lightly. If the FO was incapacitated I believe very few Captains would fly a go-around in reality - SOP or not.
At the end of the day its an emergency situation and should be handled as such.
