Ollie, it's simple "the more you do something the better you get at doing it."
I'll say that again
THE MORE YOU DO SOMETHING
THE BETTER YOU GET AT IT
Instead of worrying that the software is holding you back, look at what things you do not know how to do yet, whether it be composition (melody, chords, rhythm), sound design, mixing, creative eq, creative application of effects, etc
When you have made your list, decide which facet you want to tackle first and so on: set yourself an agenda for learning within your current daw.
Changing software won't fix anything, it will only highlight different aspects of the same basic problems; it's like changing boats mid-trip or horses mid-race - very difficult and usually not worth the ensuing pain.......
