Yes. I owned and gave away the Lodge Double Dutch Oven, recommended by various books and predating the Challenger, because it only made boules. I considered and rejected the Fourneau Bread Oven for exactly the downsides they note. The Challenger just works, and it bakes bâtards.
I used to always bake a pair of loaves and give one away, which favored my aluminum disk in a cake pan for steam. I now bake one bâtard at a time, which favors the Challenger. The KK appears to handle my steam method just fine, but when we spent more than my first two cars on an Italian range for our kitchen, we blinked. We'll still use my steam method for free form baking in the KK, but like @Pequod the Challenger has become my default both inside and in the KK.
