Where each one falls short

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

PubNub

Treblle

No free tier is offered; the entry-level Core plan starts at $233/month billed yearly.
Growth and Enterprise pricing is custom and not published, requiring a sales conversation to budget.
Core plan is limited to 1 workspace and only 30 days of data retention.
SSO and on-prem/BYO cloud deployment are reserved for the top Enterprise tier.
