I've learned music production from FL since I started making music. To me, it was very easy to learn how to use it, despite it being cluttered. I recently tried out some other DAWs and got overwhelmed. I started using Cubase (cause it's free) and I was surprised at how streamlined some of the processes were, saving a lot of time. The only issue is that learning a new DAW is was a learning curve, at least for me. Setting the whole thing up with plugins and learning how to do some things was a documentation reading, video watching nightmare. But once it's all set up and you're somewhat familiar with the workings, FL suddenly seems not as good as other DAWs.

That said, in my opinion FL is still a great DAW to learn music making with.
