Hello. I used to freestyle a little bit but never got really good (nothing beyond TATW).
For me, it's more about style and making the moves "your own".
What I mean is, there are freestylers who just perform simple tricks - but never falter and make it look effortless.
Also, some people are good at ground moves, others are good at stalls, etc.
So it depends on what direction you want to go in.
