No Decent GTD Task apps?

I was old school android at one time, went through several droids until iphone came to verizon. Well now Im thinking of going to the s4, but I cant see to find any quality gtd apps? Astrid is nice, but Im looking for something along the lines of omnifocus. Any suggestions?

My app Do It!. It syncs with Google Tasks and allows for multiple users and has a lot of the bells and whistles as many of the other tasks apps. The pro version has many additional premium features, but the lite version should work fine for most users.

Does it follow the GTD flow? I dont have an android phone yet, Im on iOS. IF I come back to android, it would be on the Samsung GS4. THanks for the reply!
