We started with an Oster and then purchased a Cosori
While the Oster was good, I absolutely love the Cosori. I feel like the non-stick coating on the basket inside started to deteriorate on the cheaper one. The Cosori hasn’t had that issue. Also, I think it cooks a little quicker than the Oster did.

My dad, sister and I all have the same one. I love it, but if you do get this one do take care of the basket if you want to increase it's lifespan. I only use the non scrubby side of the blue sponge and dawn soap to clean it and it looks as good as new after 2 years. But my sister used the heavy duty yellow sponge with the scrubby side and the non stick isn't as good.
The Cosori will meet 95% of peoples needs.
Start with that and then decide if you want something else.
