Just because they don't feel the price is right/competitive doesn't automatically write them off as not your target market/ICP - it could still be very valid feedback, especially when competitive options may be cheaper.
Personally I pay less than 1/2 the sub rate they're charging for TickTick Premium, and love it. That's not to say I wouldn't pay double for what it gains me (I definitely would), but given that TickTick is a viable option - I don't need to.
Hope you enjoy - I've been on it for a few years after bouncing around a variety of tools and I really have no major complaints. My main concern is risk of eventual bloat, but so far it hasn't been an issue. I feel like it does a good job of letting you pick and choose what you want to use, hiding the rest.
Side note: although TickTick supports notes, I don't use them. I dig UpNote, another not-super-well-known but simple, cross-platform, and inexpensive tool. It's basically the feature-set I wished Evernote stopped at (super subjective, maybe too simple for most here).
