The most common mistake in this comparison is treating it as encrypted against not encrypted. Both use strong end-to-end encryption for message content, and the same underlying protocol design. The differences are everywhere else, and they are substantial.
Same content protection, different metadata exposure
Message bodies are protected in both, which means neither provider can read what you write. What differs is the information around the message: who you contacted, when, how often, from what device and network, group memberships, and how much of your address book has been shared with the service. That layer is not covered by content encryption and is where the two products diverge most.
Metadata is not a lesser concern. A record of who spoke to whom and when is often more analytically useful than the content itself, which is why a comparison that stops at encryption has skipped the part that actually distinguishes these applications. The evaluative question is how much each service is structurally able to know, not what it promises to do with it.
Ownership and funding shape the incentives
One is operated by a non-profit foundation funded by donations and grants, with no advertising business anywhere in the organisation. The other is owned by a large advertising company with many other products, and although message content is not readable, the surrounding account and usage information exists within a corporate group whose economics are built on data.
This is not an accusation; it is a structural observation that predicts direction of travel. Where a company must eventually monetise, the pressure over years is toward collecting more rather than less. Where an organisation has no such requirement, the pressure is absent. Choosing between them is partly a bet on which trajectory you prefer over the life of your account.
Backups are where encryption is most often lost in practice
The most frequent real-world leak in encrypted messaging is not the transport but the backup. A conversation encrypted in transit and then copied to a cloud backup in readable form is available to whoever can reach that backup. Both applications offer encrypted backup options, and the crucial detail is whether it is the default and whether both participants have it enabled, since your correspondent backing up in the clear exposes the conversation regardless of your own settings.
Check the backup configuration on both ends of any conversation that matters. This single setting undoes more encryption than any weakness in the protocols, and it is invisible in every feature comparison because it lives in a submenu rather than on a marketing page.
The practical trade, and the sane resolution
The privacy-maximising option is worse on reach, and reach is what a messaging application is for. An application nobody you know uses provides no privacy benefit because the conversations simply happen elsewhere. This is the network effect that keeps the mainstream option installed on nearly every phone and it is a genuine, not merely social, consideration.
The resolution most people land on is using both deliberately: the widely-installed one for ordinary coordination where the participants are what matters, and the privacy-focused one for conversations where the metadata itself is sensitive. Moving a specific conversation is far easier than moving your entire social graph, and it captures the benefit where it actually applies.
