I've never actually used an expensive rice cooker, but the $15 one I got at [department store] works perfectly for me. This video sold me on the beautiful simplicity of it, and it's my favorite kitchen instrument
My wife forbids me from getting any large appliances for any 1 thing, so I could never convince her to get a ride cooker. Instead we got an InstaPot that we use exclusively to cook rice. It's way different (trust me)
There’s definitely nuance to how you do it in the instant pot, depending on what kind of rice it is. Zojirushi is a little more hands-off, and fool-proof. I just never decide 2 hours in advance that I want rice with dinner.
I have an instant pot as well, and used that for rice too. But it is nice to be able to have beans in the instant pot and rice in the rice cooker at the same time.
