Read every alternative volunteered here. Imagine any world where in the next 5 years they can't be enshittified, sold to a predatory private equity, their support lines AI-ified, their headcount reduced by 40% without your knowledge, etc etc. 27 years is a very long time.

A competent IT person can have a backup plan for every expected failure. They can't control registrar level screw ups.

Companies explicitly selling you "bulletproof domains" like MarkMonitor have screwed up big time.

Also as an IT guy, asking to register a new domain with X is much easier than asking to transfer a long held domain away from Y.
