You should always be on the latest as it includes security updates. No need t wait,
CU21 will actually be last the 2016 CU:

Every install is different, but CU19 has been out now for two months, which means Cu20 should be out soon. I would rather put Cu19 on now, then you can wait after that till CU21.

CU17 was released 8 months ago, I would upgrade.
Just be sure to follow the best practices:

Hi @SathishkumarSingh-0068 ,

Yes you could upgrade to CU19 directly. It is recommended that users should always use the latest version, but since installing the CU would be a full setup, I would carefully consider Andy's suggestion.

Regards,
Lou
