I'd probably go with

Karen - Mark
Lilia - Matt D
Nicole - John Barnes
Flavia - Matt DA
Camilla - Tom
Ola - Spoony
Erin - Colin

Ian - Zoe
Matt - Alesha
Anton - Patsy
Darren - Jill
Vincent - Louisa (just about, over Rachel)
James - Gabby (though Cherie was excellent)
Brendan - Kelly

Just to tot that up:

Karen - Ramps 22
Lilia - Matt D 10 Gough 7 Aled 4
Nicole - John Barnes 6
Flavia - Matt DA 22
Camilla - Gethin 17 Tom 4 James 1
Ola - Spoony 18 Kenny 4
Erin - Colin 17 Austin 3

Ian - Zoe 20 Denise 2 Jodie 1
Matt - Alesha 22
Anton - Patsy 11 Lesley (Garrett) 9 Kate 1
Darren - Jill 23
Vincent - Louisa 19 Rachel 3
James - Gabby 11 Cherie 10 Georgina 1
Brendan - Kelly 14 Natasha 4 Lisa 2

I'm a bit surprised that there aren't more people who think Tom is on the same level as Gethin. Also I'd have expected Denise to do better (though didn't watch all of series 2 myself).

Karen: Mark
Lilia: Matt D
Nicole: John B
Flavia: Matt DA
Camilla: Gethin
Ola: Spoony
Erin: Austin

Ian: Zoe
Matt: Alesha
Anton: Lesley
Darren: Jill
Vincent: Louisa
James: Gabby
Brendan: Natasha

Now this is interesting. What does "best" really mean?

Anton - Has to be Lesley Garret really (although Patsy Palmer was fairly good.)
Erin - Colin, easily. Austin's good but Colin was special.
Camilla - Tough one. Tom's probably better technically but I'd rather watch her with Gethin any day.
Ian - Zoe Ball (although Jodie is probably the most likeable partner he's had.
Darren - Jill Halfpenny (no arguments necessary)
Lilia - Darren Gough (Most watchable, even though Matt Dawson was a better ballroom dancer.)
Matthew - Alesha (Total no-brainer)
James - Gabby (Potentially best overall technically, even if she didn't captivate me personally.)
Ola - Spoony (Wow, she's had a rough ride with partners.)
Flavia - Matt D (Another no-brainer.)
Vincent - Louisa (Most watchable. Rachel is better technically but I'd vote for Louisa.)
Brendan - Possibly Lisa. (Think she's marginally better overall than Natasha and she's more watchable than Kelly.)
Karen - Err Mark? Maybe?

Matt: Alesha
Ian: Denise
Vincent: Louisa
Darren: Jill
Anton: Lesley
Brendan: Kelly
James: Gabby

Nicole: John
Camilla: Gethin
Flavia: Matt
Lillia: Matt
Erin: Colin
Karen: Mark
Ola: Spoony

I think these lists show a few things.

1) Camilla & Brendan have had A LOT of good partners between them. Quite frankly only one final apperance between them is rubbish.

2) Series 3,4 & 5 were all ridculouslly strong.

3) We're being told this series is really competitive, but clearly we don't have any really exceptional stars.

4) Ola needs a good dancer. Or the Jordans need ditching.
