Each of these opens with what the other app does better, and means it. Where the honest answer is “use the other one”, the page says so — there is no version of this that works by pretending otherwise.
FoxDL vs VLC
If all you need is a player that opens anything, use VLC — it is free, has no advertising, has no paid tier, and its source can be read by anyone. FoxDL overlaps with it on playback and differs on everything after that: downloading, managing files, IPTV as a catalogue rather than a playlist, and an encrypted vault.
VLC for Mobile, by VideoLANFoxDL vs Infuse
Infuse is a library app: point it at a server or a Plex or Jellyfin instance and it presents your films and series with artwork, descriptions and progress synced across devices, on Apple TV as well. FoxDL is about getting files onto the device — downloading, transferring, managing — and playing what arrives. Different problems.

For MP4 and MOV files, downloads that finish while you watch them and music bought from Apple, the built-in apps are enough and nothing here improves on them. The gap is specific: containers iOS never learned to read, transfers that must survive leaving the app, an M3U playlist, and files you would rather nobody saw.
