I had to look it up how to choose FS type. Ghis doesn’t make it “user friendly”.
Maybe the basic workflow of basic installation is better than the older one under some aspects, like having it one step after another, rather than the older having a bunch of buttons to change stuff.
Also, to make partitions, it’s no more possible through the installer itself. You need to use an external program (eg. Gnome Disks or Gparted).

For me it’s a regression.
