This should have been obvious enough, but apparently, the fandom is blind. It's literally scientific. Natural red hair and green eyes alone have Rachel winning the genetic lottery, not to mention Percy, who has seen many goddesses found her to be extremely beautiful. The only reason we have to even debate this is due to toxic Annabeth stans who seek to deny anything that puts Annabeth in a lesser light, which is basically in most things.
The only reason Percy claimed that Aphrodite looked like Annabeth was because he's never seen Rachel, who is actually the hottest woman in the Riordanverse series, other than Zia Rashid, and sometimes Alex Fierro.
