Is this kyusu the best design?

There's no complicated, intricate structure to collect dirt, and it's easy to clean because the body is bowl-shaped, not ball-shaped, there are no flanges on the inside of the body or the lid, and the filter is attached to the lid, not the body.

It doesn't require a strainer, and there's plenty of space for tea leaves.

It has an ergonomic side handle.

I got this a week ago and I'm very happy with it.

What do you think of the design of this teapot?

Addendum: Ah,what I'm saying is that I'm interested in the functions and performance of teapots, so I'd like to hear things like, for example, about problems that arise with bowl-shaped teapots, or the advantages and disadvantages of teapots with faucet-shaped spouts and those with a beak-shaped rim.
