To begin, I have been a longtime Windows Media Center user ever since Microsoft put out WMC in Windows XP about 15 years ago. I set up a cable card tuner and watched TV and DVR recordings on it for a long time.
Then about 5 years ago, I discovered Plex and I loved that it had such a user-friendly interface on its client apps that even my wife and child was using them constantly. I think every tech savvy user feels an overwhelming pride when less tech-savvy people begin using whatever it was you've been spending so much time on. They just used it because of the nice and easy experience of being able to watch whatever they wanted to watch. With Plex's remote streaming, we were able to watch all our movies and TV DVR recordings anywhere in the world instead of just being able to watch them at home (with the old Windows Media Center).
Then about a week ago, I installed Emby. Before that, I have been joining discussion forums on different boards about other media streaming software. I just wanted to have an alternative to Plex not because I had any problem with Plex (it's still great!) but because I just wanted to future-proof my home media setup in case that something happens and I do have a problem with Plex. Enter Kodi and Emby. Kodi is very popular and do have all the Add-ons one could ever want but remote streaming personal media with it thru SSH tunneling is no easy task (it's not a built-in feature). Also, my family members for some reason just gravitate towards using our Apple products (iPad, iPhone and appleTV) instead of our other devices and Kodi is not supported by Apple. I have sideloaded Kodi to all our devices but the whole procedure was too clunky and I gave up after my Apple developer account expired.
So I am using Emby for about a week now and have been loving it. I love that it is open-source so that anybody could just make a fork of it if and when the developers get too greedy and try to become commercialized.
I'm hoping to start this topic so that anybody else who's evaluating Emby vs Plex could just add in with their thoughts on which is better...
