That’s a poor statement to make without giving any evidence. I use both Debian and Opensuse for decades in production environments. Both have very mature package management tools. Can’t remember that they have failed me ever. Back in the days Opensuse’s early zypp had problems, but that was solved in 2008.

It should better read “Intel bugs cost you 16.67% of your GPU performance.”

You may want to check out openSUSE. It does this on a system where / is encrypted but /boot is not.
