Brex vs. Mercury – how do they compare?

Brex has a comparison page where they claim superiority in every category, but it's clearly one-sided. I wish Mercury provided a similar page, but they don't. As of September 2024, how do these two actually stack up?

For context, we're a funded startup with $300k in cash—below Mercury's $500k threshold for treasury services but acceptable for Brex. Other than that, I love Mercury's UI and automations, at least based on their landing page.
