Been plucking at the guitar (literally and figuratively - trying to learn) for a couple of years now and Justin's (free) course was the best I've found. His videos are compassionate, funny, explain things really well and easy to follow. He also dog-fed the instructions by learning to play left-handed (and posted those videos as well, hilarious to watch).
Compared to that, some time earlier I subscribed to a Berklee free course on Coursera (iirc) - Beginner guitar. Felt like a fumbling idiot, almost never touched guitar afterwards.
Another 10/10 free course is Scotty West’s Absolutely Understand Guitar on YouTube. Filmed in the 90s and it’s still one of the best classes out there.
If you can afford it and have the time, your local conservatoire.
Piano is very different than the guitar, it is much more technique and repertoire focused (as opposed to improvisation and interpretation of guitar).
In comparison to guitar, there is much more and much higher quality material available for piano as it is being taught for hundreds of years, but most of it is accessible through classical teachers.
There is definitely opportunity for someone to create the justin guitar of piano though, I do not think it has been done yet.
