Impact: Both 1 era artists but Alesha had the biggest era & peak back in the day. Alesha also managed to have more success as a solo act compared to Tulisa who was also from a group.
Singles: Prefer Alesha's singles from The Alesha Show (especially Lets Get Excited which is underrated). Young by Tulisa is her best and I liked that song that Daniel spams on plug.
Albums: The Alesha Show is a tad better than The Female Boss (or whatever that mess with British Swag on was called). Tulisa's album artwork > Alesha's though
TV Judge: Tulisa wins this one!
Overall: Alesha
