OpenSUSE, mostly because they differ too much from other distros, often even without any (obvious) advantages.
For example a lot of file paths (config files and such) are different, and when being used to other distros (or just following a guide from the internet) it takes longer to find it (I know there is Yast but I’m not a huge fan of that tool either)
Also, Manjaro
It was possible to download lossless FLAC files (they got them straight from Deezer) though, so higher quality than anything downloaded from Youtube etc.
