You can't comparate jennifers succesfull with xtina the last decade:

2011 on the floor (youtube 1.8 billions- #1 in 32 countries)
2011 i'm into you (450 global streams + 3.6 units worldwide #9 on uk gold by Riaa )
2012 dance again (6.073.000 units worldwide)
2014 booty (Platinum by Riaa #18 billboard)
2017 el anillo (500 million global streams #1 on latin charts)
2018 ain't your mama (0 promo single - gold by Riaa youtube 800 millions views)
2019 it's my party tour (record on miami also won latin world tour of the decade)
2020 Superbowl

Plus jennifer is a worlwide Icon in music, fashion, movies.
Xtina is just a great singer and maybe the best voice of our generation but not succesfull at all like she used to be
