Basically,having thought about it, Sara was definitely a more solid perfromer than Helene up to Week 8. I'll tuk through it...
Week 1: They were both in the background.
Week 2: Sara was in the background whereas Helene pretty muchheaded the door to door sales team.
Week 3: Sara, I admit was one of the best PMs this series. Helene did the tasks she was given, and defended Sara in the kitchen.
Week 4: Sara was quite in the background again. Helene in my opinion was quite a good PM. All this 'Helene tried to engineer Lucindas firing' is rubbish. The three jobs were sales, photography or backroom, none of which Lucinda was good at, and therefore she would probably have gotten into a scrap with Helene either way. I admit Helene could definitely have done more to help Lucinda though.
Week 5: Sara was working in the kitchen on the first day, and so was Helene. They both did their jobs the best they could. On. The second day, I remember seeing a few sales from Sara, but not from Helene...
Week 6: Sara didn't contribute a lot, she did put forward a few ideas whcjh were shut down, but she could have done more, although I understand why she didn't because she was working with the most terrifying group of people

. Helene was invisible on this task.
Week 7: Sara did some good negotiations, Helene did none.
Week 8: Helene was a bad PM, bur then Sara was a sh*t salesperson.
Then, after Sara was fired, Helene was the star performer of week 9 on Renaissance, coming up with the fantastic pack alongside Claire, and doing a good pitch alongside Claire. I say that Helene was better than Claire though because Claire came up with a name that let the team down.
Helene also put in a very good interview performance, and led her team well in Week12.
So overall, looking at this, you have to admit Sara was only a bit better than Helene!
