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
