Oh how I'd beg to differ.

Debian Stable is pretty good and maintains a good number of backports.
No, it's not as anal as RHEL or SLES, but is serves a different focus.

As far as CentOS, it strives to be RHEL.  Read what you want into it,
but when the CEO of Red Hat says something positive about it, and notes
that Red Hat has to keep delivering additional values to the customer,
it means they are doing a fine job.

This is a footnote in a LPIC-1 course.  It's a good point, and should
be noted, but in reality, IHV/ISV and various security certification is
another matter entirely, separate from training.

Depends on the environment.  But yes, where you're going to be deploying
and the app doesn't change for 3+ years, agreed.  For more dynamic
environments, I have to differ.  This too should also be a note.

Debian and CentOS are fine choices for LPIC-1 training.
