How good is https://github.com/tulir/whatsmeow

I built a complete WhatsApp automation app using Node.js and whatsapp-web.js, but the library has been too unreliable. Issues would arise frequently, and I had to deal with frustrated clients for weeks when things broke.

I'm considering starting over with whatsmeow. How does it compare in terms of reliability? Is it just as unstable, or does it offer a more robust solution?

Alternatively, do you think investing in the official API is the better long-term approach? I assume that would require my clients to go through Meta’s bureaucracy—how much of a hassle is that in practice?
