I had thought about mentioning Trello. Part of my job is being an Atlassian solution provider for my employer (Atlassian now owns Trello). I configure projects in Jira, Jira Service Desk, Confluence, and (to a lesser extent) Trello. Most of my time is spent in Jira Service Desk and Confluence. We don't have that many users licensed for Trello yet, but I have a feeling that will be coming. I have configured similar solutions in Office 365 using Office 365 Groups, Teams, and Planner (Microsoft's Kanban task manager).
The strengths of Trello, Jira, and Planner are in the collaborative capabilities and integration capabilities. They are also better when you want to add attachments and multimedia to a project. Although it is possible to attach files and link to multimedia in TickTick, I think such additions look better in a product like Trello. I think of Trello, Jira, and Planner as better overall for collaborative projects (although they are not the same as more complex project management tools). Of course you can use a task manager to manage projects and a project manager to manage tasks, but different tools have different strengths. In our org our project managers tend to use Microsoft Project for the big picture project management tasks, dates, and resource/budget allocations. Various workgroups/teams in the project use Kanban boards. Jira Service Desk manages operational incidents, problems, and changes; but it integrates with the project issues stored in Jira or Trello (or even Office 365 Planner).
As a personal task manager I still favor TickTick. I've played around a little with using Trello or Office 365 Planner for personal task and project management... but I find that TickTick to be the better personal solution for me these days. It scales really well between iPhone, iPad, and desktop Web browser so I a lot of it has to do with the easy of use and viewing on any platform. I also find TickTick to be among the most flexible products I have tried for creating custom filtered views. As someone else noted earlier, it would be nice if TickTick supported integrations with other tools. Other than that it's a darn near perfect task manager. At least for me. This kind of thing is so personal that the perfect tool for one might not appeal to someone else.
I might consider Trello for managing a lot of household projects and things if I could get my wife interested. I think I need to improve my pitch, because it drives me crazy when we share all the information about a project via iMessage or shared docs/sheets (whether it's planning a birthday party for one of the kids, or remodeling the bathroom). I keep forwarding that stuff to Ticktick, but I can't get her to use that with me either.
