After working with OF for years, I got tired waiting for v2.0 to appear. The old OF user interface is really way out of date.
After playing with about a dozen alternatives, I found FIRETASK fits best my requirements, is easy to handle, has all functionality needed, is easy to navigate and use, is not as complex as OF is, but also not as lean as Things is.
To switch from OF to Firetask is also easy: just drag and drop your tasks.
Last not least: When you work with a piece of software on a daily basis, it also looks nice and appealing.
Wish list: Subtasks. Attachments.
