How we compare Astro vs X

[sarah11918]

As was noted in a Docs discussion, Gatsby has a pretty cool page (that I can't seem to get to by navigating their site, so maybe it's "hidden" and not intended to be live?) that is worth considering as we decide how to help readers choose Astro.

We had discussed "better" ways to make a page that:

realistically promotes Astro (ie not super-click-baity-hype but being clear and not shy about it when we CAN do things and DO compare favourably)
adequately informs readers who NEED this information to make decisions re: which framework to use.
It's not an absolutely "neutral" page; it SHOULD promote Astro. But, with honesty and integrity.

We had also talked about the importance (or lack thereof) of numbers. (Do the tests mean anything? Can we control enough variables? etc.)

So, just throwing this page here to help us consider all this going forward!
