Haha, true - this entire experiment works best if you fully commit to the Apple ecosystem, including apps. I know of Apple power users who use more powerful third party apps for TODOs, but still use Reminders for a portion of their TODOs just because it integrates best with Siri.
It's definitely unfortunate that Siri isn't as powerful with third party apps, that's what led me to try and stick with Apple's default apps as much as possible. So far it's worked well for me, I'm not too opinionated when it comes to a TODO app, but it may be less than ideal for others.
