Zoji works great, and they usually provide ample replacement parts in the market that they're in.
Cuckoo, korean brand, hit or miss, as long as there's replacement parts, it should be fine.
You're mostly interested in replacement silicone seal caps that go under the lid, the silicone wears out over time. If you can't find the right caps, the cooker won't work well.
Induction heats more evenly, but it does not cook significantly better unless the coils are spread taller surrounding the inner pot. The lower end models don't go up as high, they're mostly near the bottom. Induction is coils that cause the inner pot to heat up instead of resistively heating the base.
Smaller rice cookers cook better than large ones, Unless the large one is a premium model with very high 1200-1500 wattage.
Larger 10 cup 800-1000 watt models may not cook as well as smaller 5.5 ones of the same power.
The latest NEW HOTNESS, is Zojirushi's Flame Dance Induction models. These have an alternating algorithm and new base coil geometry which stirs the heat inside the pot. This will produce more evenly cooked rice if you DO NOT Pre-soak, If you Pre-soak, the function is effectively useless.
The flame dance is a time saving feature depending on how you organize your rice cooking. But you'd have to be very high lvl, like 60+, to eat enough rice to warrant buying this. And to be clear, it does NOT produce superior results if the rice is presoaked.
There are pressure cooking functions, but it's mostly a gimmick, because rice cookers are not very good pressure cookers.
The Chinese brands have caught up, but they might not offer parts in your market, so don't buy unless you see they sell the silicone caps.
Zoji and Cuckoo are expensive, but they make the cheaper lower end models, these are often much worse than the China off-brands.
Toshiba is just made by Midea, so if you're gonna buy toshiba, just get Midea.
Tp4 recommends whatever induction model that's 1000+ watts that your local costco sells. Easier to exchange or get warranty replacement.
Make sure to level the rice cooker before cooking, place the level on the inner pot, you have to level both axis.
You have to be careful with the pots. The coating is teflon based, so wash with something soft, take care not to scratch it with anything.
The keep warm function will wear out the silicone lid faster. This matters if you don't eat all the rice right away.
