I'm also a big fan of the bot API. I think it's very elegant in its approach to solving the problem of spam (bots can't really initiate chats, they can only respond to messages, or post to chats / groups where they were directly invited by a human). The performance and convenience of their desktop app is also very good. As a "I'll use it if I have to" WhatsApp user, I find having to re-authenticate the web app basically every time I launch it, and it constantly complaining about me switching off WhatsApp on my phone is almost a dealbreaker.
