If you live in a household that cooks rice once or twice a day every day, it's easier to have a dedicated device. If it saves you 2-3 minutes each time because you don't have to measure the water or watch the timing, then it's worth it after your 300th pot or so. If you eat rice only occasionally, then it's probably not worth it.

I did, at one point, have a multi-purpose rice cooker that had all kinds of setting similar to an instapot. I could put rice, mean, veg and cook the whole thing without attending it. It was nice, but when it broke down I didn't replace it.
