Aroma stainless steel for a cheap rice cooker that will last forever but will make bad rice if your water rice ratio is off by a little, if you wait too long after it finishes, etc.

Zojurishi for top of the line premium quality for a premium price.

There are some other Japanese and Korean premium rice cookers that make rice just slightly worse than zojurishi but have a much cheaper price (relative to zojurishi). Tiger and Sakura are two of them.
