Which is better, an iron pot with two ears or a single handle?

I'm used to using a single-handle iron pot. In fact, this is relatively simple, and it feels more convenient to use as a whole. In fact, the overall function of the double-ear iron pot can also be used to steam some things, so it can generally be used according to my own preferences. I think it may be better to use a single-handle iron pot at ordinary times.
