For example the UI of SX Installer is miles ahead of Goldleaf and Tinfoil doesn't even have a GUI. And Goldleaf only supports installing one title at a time over USB and makes you approve the install every time on the Switch. I wanted to install some games overnight so that's no good.
SX Server is pretty nice too, just point it to a folder with nsps and SX Installer on the Switch side automatically detects them and lists them the same way it does with nsps on SD card (grouping game/update/DLC per game and letting you queue as many installs as you want), only thing I miss is an "install all in folder" option.
