well, you can thank me for the zipper and double bottom on your hh if you want, they never had options like that before the bb was around.;)
actually, the "smaller" model hh's "are" comparable in size to the BB's. notice their smaller models (up to 6') have a 100" RL, basically the same as the BB (rated to 6'6"+), and i'm almost positive that the hammock body length is very similar too if i recall. their larger models have a rl of 108" and up, so if you wanted to compare apples to apples you'd actually be comparing similar "sized" hammocks, not similarly "height-rated" hammocks.
comparing the BB to your DJXL is a poor comparison because the DJXL is signifigantly longer (about a foot longer i believe), so when someone makes a comparison between the expedition and the BB, that is a "fair" comparison because they are basically the same size.
