Thermal relief vs "THT thermal"

What’s the difference of these two? They seem to look about the same when I look at the rendered view. I’m doing only THT for this pcb, but both default and the tutorial I’ve watched used the one just named thermal relief and not THT thermal. Which should I pick?

THT thermal will make a solid connection if you place an SMT part . For through hole parts both options do the same.
