I'll give a contrary positive review for Sense. Mine has found enough household items that I have a good idea of where my energy is going. There are some items that need to be used in conjunction with Kasa smart plugs to be valuable though. For example, Sense isn't good at detecting modern refrigerators, dishwashers or washing machines.
I'd still recommend the Emporia if all of your breakers are in a single panel. It's much cheaper and would give you results much faster. Sense does better if you have multiple panels.
