I have tried a number of to-do apps and always felt like they did too little or too much. Any.do us so customizable you can use it how it best fits for you. I just finished planning a wedding while buying a house and working a large freelance job on top of my day job—stressful to say the least—and I couldn't have stayed on top of everything without Any.do. The categorizations, syncing with Chrome, reminders and shared tasks were life savers. There are a few bugs here and there (e.g. I can't add tasks under one category without it crashing) but they're minor and easy to work around. I would highly recommend this app to anyone!
