Yeah, they do largely fit into pairs:

BJ / 7800 - Darker, grittier pop/rock/metal
SWW / NJ - Stadium sized anthemic 80s rock
KTF / TD - More blues and hard rock edged, more grown up but still incredibly passionate
Crush / Bounce - Both somewhat hit-and-miss attempts to experiment with contemporary sounds, and remain relevant in a changed musical landscape

Then HAND, which saw them settling comfortably into a modern commercial rock style ... which, while it did make for the most consistent post - 2000 album up to that point, also made it the most "safe" of the three

Then LH .... basically adult contemporary music with a bit of classic BJ pop-rock and a bit of country influence

So I guess the HAND / LH pairing is something like: radio friendly modern pop-rock
