It's not dark at ALL, IMO. Unless you're comparing it to other Chinese LDCs.
47s I've used, as well as 49s ARE dark. Maybe they're old...but, Korby's 47 sounded pretty much right in there with them. 67s/M269s....not so much. Darker than your cheapo LDCs, but not "dark". That's the thing about discussions with new(er) engineers. If you've grown up using Rode and MXL and such mics, a 2247 will be warm and full and dark.
So, hyperbole? It certainly has a mid forward push like an old Neumann...so do a lot of mics.
The Mojave sounds a lot like a 67....they managed to get all the qualities without any of the qualitY.
I think if a 2247 beats a U87 in a vocal shootout, you're not listening in the context of a mix. Or maybe you have an AI without a well matched preamp. Or you just don't like the 87's sound.
You certainly don't have to agree with me. I want to be clear--I don't think it's a "bad" mic at all. It was a great value at $850. At $1300...ehh...I'd save my money.
