having 1 go-to tool / system never worked for me.. My favourite setup for years used to be plain text files which I'd use for brain dump, tasks etc. as it was flexible, simple and I owned my data. Though it had its own shortcomings and I still ended up using some other tools on top of it, not to mention the tools your team requires you to use.. Your whole information / time management setup becomes a mess very quickly.

Why not integrate these systems into 1 lightweight interface and make it collaborative and integrated? I'm trying to scratch my own itch with building https://acreom.com.
