swoole-php Asynchronous distributed tools

What is PHP's advanced tools in the background, in addition to its web-side?

We all recommend, say the advantages or differences?

What I know at the moment is swoole and Workerman, Gearman.

Swoole is an extended form of asynchronous tool, but the latest version seems to have removed the distributed direction.

Workerman and Swoole are more convenient than they are, because there is no need to expand, and the contrast between the two tools is unknown.

Gearman is a distributed framework and a powerful tool for PHP back-end distribution.

Are the tools stable at least, and the community active?
