Checks are easy to use: just write a name and an amount on a piece of paper.

They’re secure: they can only be cashed by the person they’re made out to (unlike cash).

They have theoretically infinite throughput: you can write any amount on a single check.

They have extremely high latency, which is why digital payments are being preferred in many situations. But the remaining situations where checks are used high latency is acceptable or even desirable.
