You know who did dragonborn well? Neverwinter Online. I created several in that game. So good. My blue dragonborn cleric with the new fallen angels wings "mount" looks really awesome.
I hope BG3 does dragonborn very well. I have high hopes for it. The look of the dragonborn in Solasta is one of the main reasons I haven't gotten the DLC yet. They just don't excite.
