Boring? Boring is good because it means the application is getting out of your way so you can work. When Live was first released, I thought I'd love it's UI but I found it very difficult to work with and nothing has really changed in 20 years from that point of view. But Live is a completely different way of working, one that I really don't like at all, so it could have the greatest UI in the history of mankind and I still wouldn't want to use it. And, like Bitwig, development heads in a direction that makes it less and less desirable for me over time. All of which means that if you prefer Live, it's got f**k-all to do with the GUI.
Or maybe it's about productiveness and any given application will facilitate a workflow that works for you or it won't? Studio One works for me because "studio". I like the mixer-centric approach I can use in Studio One because it has allowed me to develop a workflow that feels, at least a little bit, like working in a physical studio, where the mixer is the centre of everything you do. That's obviously the market Presonus are going for, where Live is about dance music, which is a fundamentally different approach.Someone said all apps are functional tools. Its a bad take. Apps have character, opinions & energy encapsulated within, they reflect the cultures of the people who make them. There's subjective but valid reasons why one might inspire you, while another might feel like it antagonizes you somehow. It's interpersonal, between your proclivities and those of the people who made it.
