Pros: The personal interaction with the team is probably the biggest draw for me. ActiveChat is one of the new players in the bot field, but they're clearly listening and responding to their early adopters via e-mail, the official Facebook Group and probably other channels as well. I am confident they will execute everything on their roadmap within a reasonable time frame, allowing us to create every type of bot we can imagine.
Pros: The visual bot builder makes building complicated bots really easy without loosing the greater picture. And with all the functions that are offered you are not limited by what the bot can do. And things you currently can't do are worked on by the developers immediately to make the product better. It is amazing how fast they pump out great updates!
