Where each one falls short

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

Pontoon

There is no hosted commercial edition, so adopting it means running Django, PostgreSQL and a task queue yourself and keeping them patched.
No vendor support and no service level agreement exist, so an outage during a release freeze is your engineering problem alone.
The roadmap serves Mozilla localisation needs first, and features outside that scope are unlikely to be built for you.
Format coverage is narrow next to commercial systems: it is strong on PO and Fluent, weak on document formats such as InDesign or complex XML.
Because you host it, security and compliance evidence such as an external audit report does not exist, so any assurance your customers need has to be produced by your own team.
