The 009s are better cans all around to my ears, but I don't know exactly where it falls on the bee -> bull spectrum. Maybe a large dog.
Anyway, I have never been a big 007 fan and thought they pretty much sucked on anything before the BHSE and DIYT2. The darkness and more "distant" presentation of the 007s is not too much to my liking -- especially on anything other than the BHSE or DIYT2 (I haven't heard a KGSSHV). Those two amps made me want 007s again, however, because they bring the 007s to life and yet the more laid back presentation is fun sometimes. Plus, you can rock out on 007s easier because of that less detailed and less forward presentation. Now, Birgir says my 007BL are the worst of the 007 lot so I guess I may have to compare some better ones for the hell of it.
I hate the 007 Mk2 so they don't even make it onto the spectrum for me.
The Omegas are much closer to the 009 in presentation, but they do not have the accuracy or control of the 009. Again, the bit of flab or lushness, depending on how you want to characterize it, is something I still love about the Omegas and makes them more fun on some level. I would never dream of getting rid of the Omegas given that I already have them, but I don't think you need Omegas if you have 009s.
I think the best combo is 009s plus 007s for a change of pace. Of course, it is also nice to have 4070s when you need a closed can, but that is another conversation altogether for most people.
