I echo this statement. I use Django a lot for my backends and I was very, very against moving to class-based views. I'm not sure why, I love OOP, but I was so used to function-based views. I finally made the switch (well, I use both when appropriate) and I love them.

During this time, I started playing around with React and I thought, I learned my lesson, it's class-based components all the way. Yet again, the community started going to "other" way with function-based components and I was steadfast in my attachment to classes - refusing to budge.

Of course, I eventually made the switch and wish I had done so sooner. Once you get the hang of hooks, they're so much easier to reason about and, as you said, make me much more productive.
