The short version

Each has a real cost: Syncthing synchronisation, not backup: a deletion propagates to every device, and versioning must be configured deliberately; Ventoy the repository ships prebuilt binaries that are difficult to reproduce from source, so several Linux distributions refuse to package it and security teams in regulated organisations will usually reject it.
They diverge on capability: Syncthing covers Peer-to-peer sync, Ventoy covers In-place ISO boot.

Where each one falls short

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

Syncthing

Synchronisation, not backup: a deletion propagates to every device, and versioning must be configured deliberately
Devices must be online simultaneously to sync, so an always-on machine is effectively required
Initial setup involves exchanging device IDs and is less approachable than signing into a cloud service
No web access to files, since there is no server holding them

Ventoy

The repository ships prebuilt binaries that are difficult to reproduce from source, so several Linux distributions refuse to package it and security teams in regulated organisations will usually reject it.
Development depends on one maintainer, so a period of inactivity leaves compatibility fixes for new distribution releases unaddressed with no second party able to cut a release.
Secure Boot works only after enrolling the Ventoy certificate through MokManager at the machine, which is a manual step at every device and is blocked outright on locked-down corporate firmware.
A small number of images still fail to boot in place and need workarounds, so a technician can discover mid-job that the one ISO they need is the one that does not work.
The data partition is exFAT by default, which means no file permissions and no journal, so a stick pulled during a copy can corrupt the whole image set rather than one file.

Answered from the vendors’ own pages

Syncthing: Is Syncthing free?

Yes, open source with no licence fee and no storage costs, because there is no server.

Ventoy: Can I still use the USB stick for ordinary file storage?

Yes. The data partition mounts as normal removable storage and files that are not bootable images are simply ignored by the menu.

Syncthing: Is Syncthing a backup tool?

No. It synchronises, so deletions propagate. Use it alongside a real backup, not instead of one.

Ventoy: Do I need to reinstall Ventoy when a new distribution version comes out?

No. Delete the old ISO and copy the new one. You only rerun the installer to upgrade Ventoy itself.

Syncthing: Do my files pass through anyone else’s servers?

No. Transfers are peer to peer and encrypted. Discovery and relay servers can help devices find each other, and relayed traffic remains encrypted end to end.

Ventoy: Is it safe to use in a company that audits open source?

Often not. The unreproducible prebuilt binaries in the repository are a genuine audit finding and have blocked approval at organisations with supply chain review.
