When comparing VeraCrypt vs KeePassXC, the Slant community recommends VeraCrypt for most people. In the question“What are the best tools/apps/extensions to help keep my data private?” VeraCrypt is ranked 2nd while KeePassXC is ranked 10th. The most important reason people chose VeraCrypt is:
Veracrypt is an on-the-fly encryption tool. Meaning that it decrypts files only when they are needed and that the files are otherwise kept encrypted the rest of the time.

Ranked in these QuestionsQuestion Ranking
Pros
Pro On-the-fly encryption
Veracrypt is an on-the-fly encryption tool. Meaning that it decrypts files only when they are needed and that the files are otherwise kept encrypted the rest of the time.
Pro Free
This project is free and users are encouraged to donate something to keep the project going.
Pro Several encryption cyphers supported
Supports AES, TwoFish and Serpent encryption cyphers.
Pro Open source code
The source code is open to review. It has already had a security audit and it did well, with small problems fixed by authors within days of being reported. Its predecessor source, Truecrypt, had a detailed audit that found its capabilities sound, completed (ironically) shortly before the TC folks decided to call it quits. Anyone skeptical or curious about what it does can see how it works, at the gut level.
Pro Support for AES code in CPU
Most Intel and AMD (and possibly other) CPUs have AES specific instruction sets, so you needn't task the CPU during the en/de/crypt process when using AES, VC throughput is as if the code were in 'firmware'; you can see the effect if you choose anything but AES as your cipher.
Pro Can create containers
It can create containers (like a encrypted folder) which is very useful.
Pro Regular updates
Veracrypt is in active development with constant and regular updates and several external audits in the planning stages.
Pro Multiplatform
Veracrypt is supported on MacOS, Linux and Windows.
Pro Built on top of TrueCrypt
Pro Easy to use
It's easy to understand and use.
Pro It is free and open source
Free. No hidden tracking. 100% Open Source.
Pro Active development
Pro Cross platform autotype
Autotype available for all apps.
Pro Strong end-to-end Encryption
Zero-knowledge. Military-grade AES-256 & Argon 2 unbreakable encryption algorithms.
Pro New secure browser integration plugins
Official Browser plugins for Chrome, Firefox, Edge, Brave, Opera, Vivaldi and all other Chromium or Gecko based browsers.
Pro Passphrase generator
Pro Easy to use
It has a really clean looking design, unlike Keepass. Makes it really friendly to get into.
Pro Good UI
User-friendly and straightforward. Easy to use.
Pro Better than KeePassX
KeepassX discontinued in 2017.
Pro Support for time-based one-time passwords (TOTP)
Pro Stores passwords locally instead of in the cloud
Don't trust anyone.
Pro Support for adding/removing SSH keys in system key agent
Pro Import and export to different file formats
Pro Available web browser extension (keepassxc-browser)
Pro Outrageous better than some paid password managers
It has plenty tweaks which lets you feel under control of your data.
Pro Portable, Tails and Whonix come loaded with it too
The preferred choice of Qubes users as well. Long story short, it's no coincidence that every one of the Linux distros renowned for it's security and anonymity features comes standard with a massive neon, blinking arrow pointing right at this full-featured, OSS, cross-platform password manager. The Slant community even lauds it as the category's second-only to what is essentially a command-line tool with a title someone could have picked out of a random spoonful of alphabet soup. Approved for Ages 8-78!
Pro File attachments and custom attributes
Pro YubiKey challenge-response support
And onlykey*
Pro Database reports (password health, HIBP, and statistics)
Pro Solid
Pro KeeShare shared databases (import, export, and synchronize)
Cons
Con Can't create volumes on the Mac.
The password used to create the volume doesn't open the volume one minute later. VeraCrypt 1.21/FUSE 3.82/macOS 10.12.6. Recreated on 3 Macs now. Unusable.
Con Not plug and play
Requires some tech savvy, so some skill is required, particularly if things go wrong. In the Windows world different UEFI implementations can cause problems in one, not in others, and the solutions are not uniform between issues. For Bitlocker, Microsoft worked out issues with vendors before hand, so if Windows installs and works without bitlocker, it will likely work with it.
Con The UI is not compliant with the Mac
This program does not use Mac UI standards. Nevertheless, it is acceptable.
Con Dark theme on macOS needs some work
The tabs for multiple databases and about menus are unreadable in dark mode on macOS.
Con Qt dependency hell
Con Browser plugin doesn't always connect to KeepassXC on the first attempt
Restarting the Browser or restarting KeePassXC fixes the integration.
Enabling "Automatically reconnect to KeePassXC" option in KeepassXC Browser Extension fixes this problem permanently.
