There are a LOT of pros and cons.

Pros:

• Developed by a professional, multi-disciplined full-time team with some security oversight.
• Hosted caching of The Movie DB for faster lookups
• Provision of SSL communication to and from your server without any special setup
• FREE EPG data caching
• Centralized server management from the web
• Low-speed relay for those stuck behind CGNAT.
• A REALLY solid mobile media player (sorry, but plexamp beats the pants off the JF alternatives)
• Centralized Login for your friends and family with email-based password reset
• 2FA already set up
• A nice reflector gauge to see if you’re ports are open and what your limits are
• Great client support on a LOT of devices
• Search is fast out of the box, even with extensive collections
• Their clients tend to do a better job supporting all the decoding features on every player

Cons:

• Not free
• Not Open
• They have a lot of your historical data and will eventually sell it when they sell the company. This is not going to be optional. That data is worth a lot and they likely already have enough EULA rights to sell it to whoever asks. Imagine if the MPAA gets in on the fun.
• Their security history is quite dicey
• The lifetime membership will eventually be enshitified as it’s not economically sound in the long run
• They constantly change the terms of the agreement.
• They constantly remove features people are using
• They constantly push to share data between users
• They constantly push Ads
• They are making previously free features pay.
• Their investors are starving, which makes them a liability.
• Their clients are generally slower.
