Mostly fluff/hype. Not a value-add over just using raw MJML (which has nice VScode plugins for live previews), and in fact a long term risk to add to a codebase since react-email is just a marketing play by Resend (a startup) and will not be maintained as diligently as MJML.
This is my experience as well. MJML is the older, more reliable, better documented technology. And when it comes to debugging email rendering, you really, REALLY want as much documentation as possible.

Also, LLMs know MJML really well.
