Daniel was terrible, and came across as an arrogant sore loser as well in his Digital Spy interview.
Beverley is very good, but sometimes she shouts which just ruins the performance for me.
Niki is on par with Beverley, but she doesn't shout. It will be interesting to see if Niki or Beverley last longer, both are equally as talented. But Niki is my favourite and above Beverley for me because she doesn't shout. Although she did strain on the final notes of My Heart Will Go On, but there are much more examples of it with Beverley.
