Where each one falls short

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

Sessions

It will not replace Microsoft Teams or Google Meet for everyday internal calls, so most buyers end up paying for two conferencing tools and asking staff to know which one to open.
The vendor is small and European, competing directly against Zoom and Microsoft, so any team standardising a customer-facing process on it should keep an exit plan and export recordings regularly.
The preparation model that makes it good is also overhead; a meeting nobody had time to structure runs no better in Sessions than anywhere else, and teams that will not prepare get no benefit from the licence.
Lifetime deals sold through AppSumo mean a segment of the user base pays nothing recurring, which shapes support priorities and has previously produced friction when plan terms changed.
It is browser-only, which keeps participation frictionless but leaves it more exposed to browser and network conditions than a native client, and there is no desktop application to fall back on when a call misbehaves.

Viber

Viber has limited relevance outside its strong regions, so building a communication strategy around it in North America or most of Western Europe reaches almost nobody.
Ownership by Rakuten ties the app to a commerce and points ecosystem, and account data can be linked to Rakuten services in markets where that integration is active.
Business Messages pricing is metered per message, so a company sending high volumes of promotional content can find costs rise quickly compared with a flat fee model.
Viber has lost share even in some of its historically strong markets to Telegram and WhatsApp, so its regional dominance is not guaranteed to persist.
The desktop client depends on the phone app remaining active and connected, which is a limitation for anyone wanting a fully independent desktop messenger.
