ZL123It's a lot warmer, the at2020 has a shure sm58 quality to it. Being that it's accurate, bright, and pretty true to sound. The MXL has a warmer softer tone with a lot of character, so even when your vocals hits a sour note it dosen't seam that bad. I've use it to record amps also and it does a good job of capturing accurate sound. Both are great mics, I use the at2020 to record acoustic instruments and the v67g to record vocals. If that makes any sense.
