Is Sui a Solana killer?

Could you please clarify for me, is Sui truly considered a Solana killer? I'm quite intrigued by this concept and would like to understand the basis for such a designation. Is there any specific feature or capability of Sui that directly competes with Solana, potentially leading to its downfall? Or is this merely a speculative claim without concrete evidence? Could you elaborate on the potential reasons behind this assertion and what makes Sui a potential threat to Solana's position in the crypto space? I'm keen to learn more about this intriguing comparison.
