Android Tasks App

This has probably been asked a few times in the past I am sure, but I am looking for an up to date review.

Recently I moved my SGS3 from TouchWiz to SlimBean ROM, and now I have the stock calendar app I notice I don't have the ability to add tasks to my calendar anymore.

Which Android Apps do you all use to manage Tasks? It would be better if the App could sync to Google tasks also, so that I can keep my calendar up to date.

I know of a few such as:

Remember the Milk, Any.Do, GTasks, DGT GTD & To-do List.

TL;DR - What do you use to manage your tasks on Android, and why?
