I've used mostly email for messaging, skype for talking, Jira for development work and MS Word for planning/documenting. Not a big fan of Slack, preferring a quick email or a call for longer discussions (or preferably in person chat, but I'm currently remote).
Haven't been happy with Jira for a long time so decided to start thinking about what a replacement would look like. Created https://tasks.withcomb.com as a placeholder to see if others are interested.
But in my research I've come across ClickUp & Clubhouse for project management. Never used Confluence, and while I don't really know what it does beyond being a documentation site/wiki, I'm pretty happy with Word to type up requirements & GDrive/dropbox/OneDrive to share with the team.
