I have both but Jellyfin is not good with duplicates. Having several versions of movies in different languages just puts multiple copies of the movies in Jellyfin, with no distinction between them until you click into the details. Plex does this well with “Play version”.
But Plex is worse for other reasons, on my LG TV. It’s painfully slow and doesn’t play the correct audio track that I select.

An mkv with multiple audio tracks would save you some storage space.
