The last time X-tina was considered relevant was "Back To Basis".
I don't think X has had a 2x platinum hit before.
Sure, she's got the voice but Britney still has the the sales, relevance and attention. Bionic and Lotus combined are yet to outsell Femme Fatale despite the fact that Britney barely promoted or made an effort to better her album sales.
Infact, I don't think any of X's recent singles have outsold Radar or Criminal.
The funniest thing is, The Xtina stans on this site fall right for BL, DMF'S etcs. trolling threads and then end up being dragged mercilessly. Like really? You're gonna come for Britney's LOOKS? Anything at all and you choose LOOKS? Quite the mess.
