Ask HN: Looking for the good project/todo management software, even obscure ones

I like the databaseless idea of todo.txt but it's very complicated to manage projects with complex tasks. Only easy todos like "walk with a dog" or "read a book". I like taskwarrior and dstask as proof of concept, but come on, to add a task with needed tags and parent I need to write literally five times as much as task is. I don't have such a good memory to remember all the tags and flags that are out there. I like Org-Mode, but I'm Vim user (un)fortunately.

So please, post here task/project/todo management software that you found really nice and useful. That have tags, maybe trees, maybe something else. CLI, TUI or GUI.
