I think they’re convenient for hanging plants, but with most of my plants I’m more concerned about overwatering than underwatering so they’re not ideal.
My calathea is the only plant I’d say truly thrives in a self-watering pot. I have a few others in self-watering pots- philodendrons, alocasias, aglaonemas- that are varying levels of ambivalent about their pots. I need to be careful not to leave them too wet and will likely be repotting them into normal draining pots.
About every other week with the self-watering pot, whereas it'd be weekly in a normal pot!
