I have no direct experience with either mic, but I've done a lot of work with the AKG 414, bigger brother of the 214, and a bunch of other AKG mics and my company has a pair of Mojave 201fets that I have used as overheads on drum kits. I can give you my own experiences. The Mojave 201fet was designed by David Royer and is a very, very smooth, sweet mic. It is a cardioid large diaphragm condenser. The 301 is a development of that mic with multi-pattern selection added via dual-diaphragm design. The AKG 214 is designed to be an less expensive, cardioid-only version of the 414. The 414 is a dual-diaphragm design and the 214 is a single-diaphragm design. The 414 is a very smooth, flat mic, that might be described as a very literal mic.
Someone on the board may have a 214 and may be able to comment further. Both companies are well respected. Which is best? Check the quote in my sig.
