Are they still both of the same calibre career wise or is one currently greater than the other?

Yes

Ariana is still and has been higher than her since 2014.

Yes

No.

Yes

I think Ariana is bigger

I don't know or care, I don't listen to none of them.

OT: I believe they are, Ariana is consistent with her high levels of success. She was above Selena but this era Selena got a platinum album, 4 top 10s, numerous endorsements ect so I consider them to be at the same level

If you dont consider them to be at the same level, then you have to agree that Selena is catching up fast

No! I feel like Selena is in the same level of Ariana in US, but Ariana is bigger than Selena WW

No Selena is the more powerful over all star...

Selena gomez is slightly bigger

selena is doing extremely well but she has been as constant as ari so only time will tell but as of now she's slightly behind

yes

No. Ariana is A list, while Selena is C/D list at best.

Ariana is still bigger but the gap is closing.

Yes

Ariana is clearly bigger
