I've never owned a rice cooker but I'm led to believe the rice they make is superior to anything you can reasonably achieve in a simple pot.
It's far easier to achieve consistent results, for sure. We have a small one and it's the best rice we can make at home without significant effort.
Cooking perfect rice in a pot takes technique, for sure. But it's not that hard, and if you do it right it comes out perfect just like a rice cooker.
Wash your rice. Throw in cold pot with 1:1 ratio of rice to water, + a bit extra to account for evaporation[1]. Bring to a full boil. As soon as it's boiling, drop the heat to the lowest setting and cover your pot as tight as you can and let it steam itself until ready. When ready, fluff it immediately.
[1]: the precise amount extra depends on your setup, tbh… how tight your lid seal is, how much surface area your saucepan exposes, etc. but usually an extra 25% will be about right
I have the same complaint about a ricecooker. It's perfectly easy to cook rice in a pot. Sure it's convenient to use the automated device, but it's wasteful.
