Rice isn't difficult, yes get a rice cooker but get a good one and use the cup that come with it . There will be marks on the side for number of cups too. The thing is the cup that comes with the cooker is smaller than the cup we use for baking so if you use the side measurement for say 4 cups it is for that smaller measure. If you use a full baking cup of rice then add water to the 4 cup line you will have too much dry rice in your machine and it will be too dry.
If you use a stove top, use a heavy bottom pan, put your rice in and turn on, have your measured water ready in a container, heat the pan and the dry rice till it is hot, do not let it color, then dunk all the water in real quick . be careful it will spit, put the lid on immediately and turn the stove down to it's lowest setting. I have a second burner on ready so it isn't too hot. and switch the pan to that one .Do not peep, let the pan stay on the burner till the time s done then take the lid off. I am not giving times to cook it as it varies with the rice and it will usually say on the box or bag.
The Oriental way of gauging water to rice is baffling but it works. Dry rice in rice cooker, then start to put water in , put your thumb in on top of the rice, when the water level is equal to exactly where your thumb bends it is right. It always works and it doesn't;t seem to matter how much you are cooking.
We could argue the ages away as to whether or not to pre wash your rice, some cultures swear by it, others swear against it.
I use several different rices but my go to regular one is Basmati and it improves with age.
