Is it the best or is it just the one you use? Have you used both? Recently? Immich has changed a lot in the past year or two.

IMO just the fact that it's a NextCloud thing kinda sucks

Having used both, immich wins by a landslide. I was initially waiting until it got to a stable release, but it's already so much better. I'd recommend anyone to just use immich.

Louis discusses his experience with Nextcloud in the first portion of the video.

For him, Nextcloud's gallery app runs much slower than Immich. The Nextcloud app only supports proxy image previews but no proxy video previews, which Immich does.

Nextcloud is so slow though, I just wish they would fix the performance of it. Taking 2+ seconds to load a file browser is crazy.

NC has also had some major data loss/corruption bugs I've been hit with, I switched away from it because I was tired of the bugs.

It actually looks great. I'm surprised to see that to be honest. But I use next cloud only as an alternative to Google drive. I find most of the times I can't make apps work and risk breaking my next cloud installation. But if it works for you, awesome 👍
