| The U87 I have is an older model... generally darker than a newer U87ai.
The pair of U67's I've used sounded great, nice top and bottom, very natural in the way they brought out the best of any source. I used them mostly for drum overheads. They're the type of mics that work extremely well for a simple drum set-up (kick, snare, and X-Y OH) in a good room. I actually preferred them to a pair of U47 longbody tube mics (in cardioid X-Y position) as overheads.
I found the U67's to be a smoother (scooped) version of the CMV563's w/M7 caps.
If I had the money and found a good pair, I'd go U67.
Yet again, like others have said, there's the tube mod for the U87 but I haven't heard it yet. I'd suspect that the cost of getting a pair of U87's with the tube mod will probably cost roughly same (in the end) as a pair of U67's.
But, I should also say that I found more general uses for my vintage U87 (stock) than I did with the U67's.
I'd be happy if I owned one vintage U87 (check) and two paired U67's (un-check).
