Ardour's UI is complicated compared to, for example, Ableton Live. For example, I have added a MIDI track and it is unclear how to add notes to it. Right clicking on a track doesn't give an option to do that.
Also on Linux it supports only rarely used plugin formats (LV2, Linux VST), for which there are little plugins.
