Personally haven’t used Infuse so this may not be entirely useful.

Big factors keeping me on Plex:

• Native clients available for almost every device (PS4, XB1, Smart TVs, you name it they probably have it)
• Plexamp
• Things like playlists, which while I can export from the sqlite DB if I really want to go, it would be a hassle to
• Linux HTPC app

Less important factors:

• Live TV (from Plex, not a HDHomerun etc) useful for background noise
• ‘Discover’ feature allowing me to see what latest movies are out 🚢⛵🧲
• Very easy to share content with others
• Casting to other devices in the home
