It has gotten consistently better for years, the core product of streaming from server your own content from server to device is and has always worked great, and the lifetime pass is an absolute steal at $120. I paid $75 a long time ago and have gotten so much value for my money.

There is a thread of anti-Plex talk all over the place that I really don't understand. I don't think there is even any XBMC/Kodi code in it anymore.

I am a longtime user of Kodi/XBMC back to the soft-modding an OG Xbox days, and I eventually moved to Plex for the client-server model. It was and still is a great piece of software

Plex just works, it's not weird at all. Also, I prefer proprietary software. It pays my bills.
