Which GTD software or service to choose?

Question

Task Management

Yes, I understand, the question is tired and the correct answer will be something in the style of "try all the options and choose what you like." But I don’t want to try all the options, and so many have already been tried.
What is required:
- an online service or software (windows / iOS)
- a simple list of tasks, a new task is added by clicking on a field in the list, not a separate button
- there are projects
- there are repetitive tasks
- there are several stages of task completion
- there are subtasks
Now I use nirvanahq - everyone likes it, except for the lack of task stages and the absence of subtasks.
There are repetitive tasks in the paid version, but they are not so necessary.
PS I think I tried remember the milk, todoist, GeeTeeDee, I don't remember what else. Nirvana is the simplest and most usable yet.

Answer 1

asana.com is the best I've seen. Everything you listed is present.
Maybe also https://www.wunderlist.com/ru/ , but I think that it has much fewer features (I didn’t use it myself, I just guess).

Answer 2

For the third year I have been trying to dump somewhere from nirvana, I have not found anything as stupid and simple. I've only seen NitroTasks, but it falls far short of it.
Everything else is too slow, either slow or the workflow is slow and confusing.
I have repetitive tasks in my usual account.
Regarding your requirements - you don't quite understand GTD correctly.
"there are projects", "there are subtasks" - this is the same thing.
"there are several stages of task execution" - there is no such thing in GTD at all. Split the task into small ones (which will be "stages").
Yet you are looking for a GTD service (and Nirvana is exactly that). There is a certain methodology, rules and so on.
I can advise you to look at Zentasks, except for workflowy. But I repeat about the slowness of one of the.
