The short version

  • Only Debian has a free tier, so it costs nothing to try first.
  • Each has a real cost: Debian community-only support; no official organisation provides paid support (unlike Ubuntu's Canonical); Red Hat Enterprise Linux subscription cost per system is significant and scales with fleet size

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Debian

  • Community-only support; no official organisation provides paid support (unlike Ubuntu's Canonical)
  • Paid professional support requires hiring private consultants; no Debian-backed support tiers or SLAs
  • No official compliance certifications or hardened distributions available; organisations requiring FIPS or DISA-STIG must implement separately
  • Stable release cycle intentionally conservative, leading to older software versions compared to rolling-release distributions
  • Security support responsibility falls on community; no guaranteed response times for vulnerabilities

Red Hat Enterprise Linux

  • Subscription cost per system is significant and scales with fleet size
  • Packages are deliberately older than current upstream, which frustrates developers wanting recent toolchains
  • The 2023 source availability changes strained relations with downstream rebuilds and remain contentious
  • Considerable overkill for workloads with no compliance or support requirement

Answered from the vendors’ own pages

Debian: Is Debian free?

Yes. Debian is entirely free to download, use and modify. No licensing fees are required, and the project explicitly commits to remaining free.

Source
Red Hat Enterprise Linux: Is Red Hat Enterprise Linux free?

The software is open source but the product is sold as a per-system subscription. Red Hat offers no-cost developer subscriptions for individual development use.

Debian: What support options are available for Debian?

Debian support is community-driven through IRC channels, mailing lists, user forums and direct contact with package maintainers. Organisations requiring professional support can hire private consultants listed in the Debian consultants directory.

Source
Red Hat Enterprise Linux: What does the subscription actually buy?

Support, security backports over a ten-year lifecycle, and hardware and software certifications. Not the code, which is open.

Debian: How long does Debian receive security updates?

Each stable Debian release receives five years of support: three years of full maintenance plus two years of long-term support.

Source
Red Hat Enterprise Linux: Why do enterprises pay for Linux?

Accountability and lifecycle. A contracted vendor answering for a CVE, and an OS that stays supported long enough to avoid re-certifying applications every two years.
