Comparisons pages: add more context besides the table

[humitos]

I just saw that Plausible has some comparison pages

• https://plausible.io/vs-google-analytics
• https://plausible.io/vs-matomo
• https://plausible.io/vs-cloudflare-web-analytics

These comparison pages have some narrative / Q&A content that look interesting. I think we could do something similar here where we explain with words some of the differences in the workflow and also the pros/cons of each them.
