My interest in TBH introduced me to the Warre hive. I'm committed to setting up a horizontal TBH this spring, but I also have two Langstroth hives with all medium boxes which I plan to use with wired frames with starter strips and no foundation. Except for the frames, this looks very much like a Warre hive to me. In fact, I can't see any substantial functional difference between a foundationless Langstroth and a TBH, aside from cheap, easy construction for the latter and a frame that would reduce the danger of comb collapse in the former. Is there any other major factor I'm missing?
