Neumann - UM70/MV692

When I think workhorse, I think original U87s. If you like your U67s but not those, there's a good chance you just don't like the solid state sound. You might get more from a modern 'clean' valve mic, like an M149 or Lauten Eden. Still, there's some solid state LDCs that are worth trying. * Original C414s are real workhorses (Comb, EB, C412s) - but they've gone very expensive for what they are. Some swear by their C414 ULSs, but ours never won a shootout on vocals. Skip anything newer than the TLIIs. * U89s / TLM170s are good if you want something modern / neutral. They're the opposite side of the scale to your M49 - but do their thing very well. * Some people really love the Soyuz 017 - but its capsule is a k87 copy, so the FET version could be too similar to the U87 for your tastes. * I haven't tried the newer Gefell stuff, but a producer brought his MV-692s in (with M62 capsules), and they sounded beautiful. Really, anything old with a nickel capsule is worth trying for vocals. They have a smoothness and 'air' that's often lacking in FET mics. But before going out and renting a bunch of mics, try some of your SDCs. They get overlooked a lot these days, but you'd be surprised how great they can sound on vocals. Often they do the "cut through a dense mix" thing better than a FET LDC.

Generally l don’t find a lot of solid state condensers flattering on vocals but the short list would be Gefell UM70, and once in a blue moon sanken CU44

UM70 (the version with the transformer) sounds super close to a 70s 87 to me

I have an mxl condenser mic that works well, but just bought a Neumann condenser mic off Amazon. In the studio, they always said they used the $4k Neumann on me. Not sure that it is a knock off, but supposedly the same one Billie eillish uses and it sounds great. Under $400.
