What is the best live chat plugin or software for WordPress (e-com)?

Hey guys!

I’m looking for a reliable, fast and easy-to-use live chat plugin, add-on or software for my e-commerce shop (WordPress + WooCommerce).

I’ve been searching through the CodeCanyon marketplace and so far now these options have captivated my attention: Live Chat by Screets, FluentChat by nCrafts and Facebook Live Chat for WordPress by NinjaTeam.

I’ve also been looking for some other options outside of Envato and I have found this one by Kayako, click here. However, what do you think about it? How well does it compare against the three previous options I have listed?

I know these are many questions, but I’d like to get the best for my shop, thanks! :wink:
