Worst for me was Chloe Jasmine singing Will You still Love Me tomorrow, and best was probably Jade Ellis!

Worst was Union J's against Jade Ellis for me, it was a complete meltdown and should've saw them be eliminated.

The Best imo would probably be Ruth Lorenzo's Purple Rain.

A lot of contenders for Worst - Overload Generation, Nu Vibe, forget their name but the other boyband from Union J's year (something 3). Also Lloyd Daniels the week Rachel A went, Union J against Jade, Jedward against Lucie and Rylan doing One Night Only.

Also been a lot of outstanding sing offs including Sara tonight. Standouts for me being Ruth's two, 'Who You Are' by Misha B, Jade Ellis, Rachel Adedeji all three times especially her last one, 'Run' for Luke Friend, 'There You'll Be' for Carolynne, 'Natural Woman' Lola Saunders and 'No More Drama' by Rachel Hylton.

Females tend to do better in sing offs but then again, on average I'd say more females have appeared in sing offs

Best ever for me personally was Ruth Lorenzo - Knocking on Heavens Door.

Everything else. Ever.

Ruth Lorenzo Purple Rain

I find it truly amusing at how Cowell claims "They have to sing for their lives now" since when was this about singing, loool - Find another line plz.

Nothing will ever touch Ruth Lorenzo for someone who lost

Best - Ruth Lorenzo - purple rain

Worst - bratavio

id say this

Saara performing alive is up there with the best of them. James Arthur vs Ella Henderson was a good sing off, shame one had to go.
