I'm using Things 3 for the moment. It's nice because it integrates also with Gmail Calendar and iCal. Truth is, I'm cycling between to-do list productivity tools every few months. OmniFocus could do anything you want, but can get quite complicated too. Things and Todoist are simple and straightforward, but are missing some essential (advanced) things. I can't seem to find the tool with that right sweet spot. I guess I love procrastinating with fiddling for the best tool configuration. That said, I also often fallback to using pen&paper, and writing in the morning the 5 things that really should be completed today, and that seems to work very well too.
