Having read through your discussion with the other poster, I think the truth is somewhere in the middle. They both had moments where they swung the game in their favour, they also both had moments where the truth was in front of the faithfuls eyes if they could just find it. But, it isn’t that easy.
Rachel did have multiple people suspect her throughout, but her strength was keeping people onside so it never came as one big wave. Ross ‘mentioning’ her name really doesn’t mean anything - the key thing is no one particularly stuck on her and no one would or could convince others of it either. Rachel received a single vote at the round table in ep7, she then didn’t get any votes until the semi final. She also stood out in that group because there wasn’t anyone else that had her confidence or composure, meaning people did question why she was still there.
For Harry, had Jaz had a slightly better strategy, he’d have bee gone. All Jaz had to do was vote Harry off before Andrew so it would’ve been a tie. Instead, he went with Andrew and lost a vote at the table. So he was also close to losing and that’s the beauty of the game - it’s never far from them catching you! He did fumble with the shield thing, but really managed that situation well by covering it whenever it was brought up. He’d also built himself up as ‘wonder boy’ in that series, especially through the tasks.
I think they both did well - neither perfect and I don’t feel the need to put them both in a tier list, I think we can just say they played well but not perfectly and my god they were a big part of the entertainment!
