Xbox Live Gold, mainly for 360 games which never leave my account and an occasional round of Red Dead Online with an out of state buddy.
Nintendo Online, for $20 I decided to try it. I only use it for Tetris 99 once every couple of months. I will let it lapse until Animal Crossing comes out as I still play New Leaf with friends and family all of the time.
I used to have Hulu, Netflix, PS+, CBS All Access, Amazon Prime, Spotify, and Apple Music. I moved onto a single purchase Plex Pass and that negated pretty much everything above.
