This is probably the best task app that there is on the market. I’ve tried many of the others out there, but OmniFocus is the best of them all. Sure some of the others are cheaper and some of the others have features that I wish OmniFocus had. On the other hand, OmniFocus is stable and powerful and has many more features than some of the others. Combines with the Mac app it is even better. The sync is pretty flawless and he’s never been a problem for me - I am using the OmniSync service. It may have a bigger learning curve than the others, but there are plenty of videos and articles out there to guide you along. The downloadable manual is also a big help, and something none of the other apps provide.
