The ones I see most often recommended are...

• Bonavita (I own this one and have brewed a lot of tea with it)

• Fellow Stagg (very similar to the Bonavita)

• Fellow Corvo (similar to the previous ones, but not a gooseneck so it has a faster and less precise pour, but also pours slightly hotter as there is no spout to drain heat from the water)

These are all going to be very similar in practice, but the Corvo may edge out the others for gongfu brewing (faster pour, hotter water), if that's something you are into.
