AlmaLinux 8 or 9?

I am wanting to migrate some existing AlmaLinux8 based CWP servers to new OS installs - due to recent security issues and possible compromises.

As there seem to have been a number of #9 issues, I wanted to ask the subject question before moving.

Shall I stick with #8 or is it reasonably painless to move to version 9?

Even then, is it safe to continue with CWP Nginx now or should I set it to the AlmaLinux repository again?

Thanks.
