Each has a real cost: Signal signal must be installed on a phone before the desktop app can be used, so there is no phone-free desktop-only account; 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.
They diverge on capability: Signal covers End-to-end encryption, Viber covers End to end encryption.

Where each one falls short

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

Signal

Signal must be installed on a phone before the desktop app can be used, so there is no phone-free desktop-only account

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.
