You know I think out of all of them A'keria has earned it the most. Quietly competent (and not in a bland, "oh how did YOU get here?" kind of way) with some top tier moments. I think the cops video episode made me LOL the most this series. She's not really overly charismatic in a way I can imagine the show would want from a winner though.
I wouldn't object to Silky at this stage, either. She's become a lot more than the screaming balloon from the start and delivered in nearly every challenge except runways.
Brooke and Yvie committed the cardinal sin of being atrocious in snatch game and despite both being incredible at what they're good at, so much is out of their comfort zone. Way too many iffy moments. Yvie is often awkwardly out of place while Brooke is too clinical and there's no natural fun in her performance. I still like them both.
It's a strong top 4, relatively. Just no standout deserving winner...again.
