I loved Wunderlist, and after the announcement of the acquisition I went looking for alternatives. It turns out, I didn't _really_ need "sub-tasks" or collaborative comments on my TODOs. All I really needed was shared lists, dependable reminder push notifications, and perhaps some location-based/geofencing features. This is all covered by the stock iOS Reminders app. I use Fantastical as the 'GUI' instead of Reminders, but basically use my e-mails CalDAV server (Fastmail) to manage my lists now, and have retained the reliability and subset of features that I needed. It's been great so far, and it's virtually free as part of your standard email/calendar service (Gmail/Calendar, Fastmail, etc.).
