I'd separate the answer by Country Of Origin, and limit my comments to large diameter capsules. I'll leave aside products from Neumann "reskinners". They are uniformly amateurish, and devalue any original Neumann capsules considerably.
Chinese capsules are still stuck in the "Project Studio" quality class, no matter the label on the mic: coarse, no fine points rendered, usually way too bright (as bright sells, at least upon initial listening, but don't ask me why: since the plague-like proliferation of MP3s, we are back in low-res audio land, like we were during the first generation of digital processors in the late 1980s. The irritating rendition of high frequencies was and is a hallmark for bad digital processing)
European capsules (aside of Neumann) are generally quite good in resolution but not so good in musicality (don't ask me what that means: like porn, you know it when you hear it).
I have posted at length about the disappointing turn MG's formerly exceptional M7 took after the PVC re-formulation in the early 2000s, to the point that MG's polyester version of the M7 beats the PVC version with better frequency balance and appeal.
Herbert Haun has consistently made his capsules with tight tolerances and to high manufacturing standards, but, aside of the one-off capsules he made for the KHE, whose design, especially the diaphragm surface treatment, was specified by Dirk and me, I am not a fan of the sound.
Australia: I keep being asked about the Beez Neez K67/47-copies. But I must admit that, since I tested one that Ben Sneesby had sent me, more than a decade ago, and which sounded very good, I have not kept up with this capsule products.
Denmark: Tim Campbell has offered more than once to send me one of his CK12 copy capsules (I am not aware of any Neumann-style capsules from him). But in the past I've always been "too busy" to test yet another product that will keep me away from serving my clients who've patently waited their turn. So, Tim: send me one, and I'll promise to stick it im my C12 tester, and listen.
The U.S.: David Josephson is a consummate microphone designer and admired AES-theorist to boot. His CK12 copies are widely praised as balanced and pleasing sounding. I do not know whether he makes Neumann-style capsules with center lead-outs comparable to the originals.
Finally: Neumann. It seems that, for me at least, the dust has finally settled on the dreaded "bass starvation" issue. All of Neumann's LD capsules now deliver at minimum a tad less bass in the 100Hz and below region, and sometimes way too little for my taste.
The overall timbre of their capsules that is so enticing, the processing of transients, guttural sounds, the reedy transmission of the rapid movements of the vocal chord - both with male and female voices - that character can be easily recognized and is on par with the best they've made in past decades, which, despite the loss of some foundational bass response, is still far above the competition.
