Here is a picture of roxy ,you guys are the best

I think Roxy.
You don't misunderstand, I love Daphne. But she is more older, than the Winx. I can imagine she as a mentor, caring older sister, soul mate or a queen. Not as a Winx girl.

I love both, but I think Roxy should be a Winx because even though Daphne is a human now, she's still the nymph of Domino. Roxy is a fairy.

Thanks for your opion

I think Daphne because she's older and more experience than the Winx so she could mentor them. Roxy, however, would have to be mentored by the Winx, slowing them down and making the Winx's progress slower. The Winx would have also gotten used to how the Trix fight and Daphne has the power of the Dragon Fire so it would be easier for Daphne. And besides if all of them plus Roxy were to fight, then the Winx would have to wait so Roxy could catch up to the Winx's level, and Roxy is on Magic Winx, whereas the Winx are on Bloomix. That would take a while... So I think Daphne

I think Roxy would make a better Winx member because she's about the same age as the Winx. Also, while Daphne is a nymph, Roxy is a fairy. Plus, Daphne's a bit too old to join Winx. I see Daphne more as a mentor or teacher to the Winx.
