I think the Focals are way ahead of the B&Ws in resolution and over all performance. The 1007 be is a bit "boom and sizzle" though and I've not been a big fan of Focals below Utopia when they need to play loud. They tend to be bright as is, but get pretty hard when pushed. The Utopias are delicious, however. I think the Diamond tweeter is good, but people I know complain about the S tweeter.
At the risk of shilling (I try not to do this, but these may appeal), if you nix one of those options and get a chance to hear NHT's Xd, you might like them - http://nhthifi.com/2006/ht-s-ultimate.html
Also pretty modular and more like the Focals, but more accurate than the 1007 for sure, and the subwoofers are included, as are the amplification, stands, cabling and DSP. Pretty exotic stuff, but the cabinets are less furniturey (for godsake, click on the Special Dark finish before the other finish burns into your eyeballs!). A 7.1 Focal/sub system like you're considering is about the same as a 6.3 Xd system and each can be done one at a time. I used to be a Focal dealer and I can say that the Xd does at least some stuff better than Utopia stuff, primarily bass quality, tonal accuracy, imaging precision, soundstage size and sweetspot size. Utopias do have a "delicious" sound to them that has great appeal and very hard to dislike. I haven't heard the new 1000 series, I stopped with Electra and Utopia a few years back. No major reason, mainly the economy slowed WAY down and I had to pick who I was going to keep because I couldn't do it all at the time. I've actually had a few people tell me, however, that they like the less expensive NHT Classic series as much or more than the Focal 1000 series, but again, good looking, but no exotic woods, don't know if that is part of the equation. One of the advantages here is matched center, matched rears, all the way around. I'm a big fan of that for HT. Same drivers everywhere.
Other options - Triads, they *excel* at sub sats, but maybe not as "catchy" as the Focals. PSB Platinum - more badass, but bigger and less sexy. I'm trying to think of others that have a more similar sound, I feel like I'm forgetting something really obvious. The B&Ws and the Focals sound totally different to me. I guess I'm curious what got auditioned and eliminated along the way because the two finalists are about as different as you could get aside from the fact that the Focals will also surrender more easily
