Tried a few different apps over 2 years but always came back to TickTick. Works well for me, aligns to me needs and I find it intuitive. I'd recommend, especially since it offers a lot of features which are premium in others apps. Unsolicited advice to anyone looking for a to-do app: there is no app that works best, no one-size-fits-all. Unfortunately you need to test a bunch and decide which works best for you.
