What's your favorite challah recipe?

I'm a conversion student and am still in the process of learning, that I'm told will last all my life. I'm guessing learning the perfect challah recipe is part of this.

Sell me on your favorite recipe. Right now, I've just been making this one: https://www.thekitchn.com/how-to-make-challah-bread-181004

It's ok, but I feel like I could do better.
