Both were huge hits in 2011 and Britney got her second #1 in billboard 100 and replaced the Kanye remix of E.T

or

The one that didn't have a rapist apologist featuring a nazi.

E.T remix is one of Katys best

that s&m remix has always been one of the worst remixes ever nasalney needed to go blow her nose

I wish Britney did more remixes and collabs like this

would die for gaga+britney

I like Britney's remix of S&M but I'll go with Ye's remix of ET

Britney & RiRi 😛💙

The S&M is unlistenable. E.T. remix slaps fawk the gossip

i will go with S&M even though it was one of Rihanna's worst . the other featured Kanye which is even worse.

Britney >>>>>>>>>>>>>>> Kanye

S&M Remix is so much better than the original, which is quite boring.

Britney second verse really adds to the song and she eats on the bridge (make my body go ah ah ah) sounds so sexy when sang by Britney

ET

Kanye's verse on ET is just so ******* good Lois ughhhhhh

TELL ME WHATS NEXT ALIEN SEX?

Both are amazing but I have a thing for the S&M remix. Yeah Britney's team was weird for forcing her to record with a cold but the remix is very good and energetic, it elevated the song. The original one was kinda boring to me

Both are bad but nothing's as bad as that S&M remix

Kanye's verse really added something to the song.

Britney remix she sounded so nasally

ET remix by far! Katy has the goat on it! It's a banger and a W song

ET easily. The ET remix actually elevates the song.

The S&M remix is horrible, it's obvious that it was a quick tactic to get the #1. The Till The World Ends is the superior Britney remix from that time.

They actually played the ET remix on the radio and used it for the music video, and it sounds way more professional.

I don't think I've ever heard the S&M remix anywhere, but the original was soooo overplayed. They clearly just rushed it to snag that one week at #1 and probably paid Britney('s dad) a nice chunk of change to record it quickly, because it sounds like AI lol

Both remixes elevated the originals. A tie methinks, both remix are perfection. I jam out to both when I'm feeling like a bad *****

Britney always sounded nasal.

ET.

Definitely the E.T. remix. Kanye's 2 verses are funny as ****.The S&M remix is a blaring and screechy mess.

As nasally as Britney sounds on S&M and how it was thrown together in an hour, it's such a bop even the remix slaps

E.T remix is great too though

Rihanna should have worked with someone else their voices sound trouble together.

Sorry Katy snatched this one
