There are over 50,000 WordPress plugins out there. It is really difficult to find a plugin stack that works well for you. Some plugins are not compatible with the latest version of WordPress. Some plugins do redundant jobs or interfere with each other. Some plugins are hard on your webserver. This article gives an overview of plugins I work with regularly including their purpose.
I do not have all of the plugins installed on every WordPress instance of course. It totally depends on the need of each individual WordPress project. Plugins I use only very seldom are not even listed here. If time allows, it is easily possible and feasible I try to find a workaround to avoid installing too many plugins.
