Most specialists, historically, use small diaphragm condensers, such as DPA. To generalise, SDCs are more accurate, LDCs are often voiced to flatter the human voice.
I originally compared a Neumann (can't remember the model but it was the same price as the next cited) and an AKG C414 - the latter although large diaphragm, was more faithful. I ended thinking it was like fizzy drinks - you might prefer a sip of one and a glass of the other; I preferred a sip of the Neumann and a glassful of the AKG.
I now normally use two Hebden Sound SDCs.
