I've self-hosted my own single-user Piped instance for about a year. However, I sometimes encounter problems with video loading times, and some subscriptions don't display new publications until I manually visit the channel. The main reason I chose Piped was because it had LibreTube for Android, allowing me to sync my subscriptions between mobile and desktop.

Recently, I've been testing Invidious and I'm liking it. I discovered that using it on Android as a web app is quite efficient, especially in combination with UntrackMe to automatically open YouTube links in my Invidious instance. Additionally, there's Clipious, an Android app similar to LibreTube but with an Invidious backend. Although it's early in its development, it performs well.

I'm still weighing my options, but I find Invidious to be more stable in terms of loading times and subscription feed updates.
