The Marshal has an edge in the breathy-upper midrange that really punches up a vocal. They are both very good at off-axis rejection, but the overall tone of the Marshal appeals to me. You really should listen first - they're all good - just with different "personalities"
I almost bought the Rode too.Don't forget the AKG c1000s - even though it's a small diaphragm, it sounds GREAT! Sometimes the added pickup range of a large D gets "too much" sound in a small studio. That's when a small D comes to the rescue. The c1000's are my most used mics right now.
