We put the three groups in Louis' category head to head and asked you all to vote, and the results are in.
Union J stormed to victory with 51% of the vote, while rivals District3 were in second place with 30%.
MK1, who we reckon really are the dark horses of the competition, held their ground with 19.
Last week saw Gary take a swipe at District3 after their performance, and the trio ended up in the bottom two.
They've been going all out this week to drum up support and focus on their vocals on a bid to avoid the elimination, but will it be enough?
Which of the groups and boybands do you prefer and why? Leave your comments below!
* well, as official as a poll on our website can be. So not really official at all.
