Which one wins for... one?
Jessie went for an embellished frock with a feathered skirt and thigh-high split.
While Cheryl went strapless and shiny with an eye-catching fishtail.
Both very different looks, both making a big statement.
Luckily, the Queen herself didn't seem to favour one over the other - although Robbie Williams has definitely spotted something he likes.
