Both are Hypercardioid. What is a Cardioid capsule? This basically means that both reject sound from the back and the sides very well, but they both require very specific placement as far as your screaming mouth goes. 😛 That said, the OM5 is more forgiving. More on that in differences.
Both reject ambient noise very well.
Proximity. The Audix OM5 has a polar pattern that is more conducive to rejecting off-axis noise. It’s tighter, and will do really well in capturing a vocalists natural voice. Because of it’s 140DB SPL, it can handle extremely loud sounds without distortion. What is SPL? While the OM5 is designed for people who like to sing right up on the mic, the OM6 is a little different. It allows more flexibility and the freedom to move around.
Mid-range. The OM6 isn’t as bright as the OM5. So if you’re a vocalist who tends to sound sibilant in the upper registers, you may choose the OM6 as it will kind of tame those habits. What does Sibilant mean?
Off axis rejection. The OM6 doesn’t have as much as the OM5 in close quarters, but they’re about the same otherwise.
Bass roll off. The OM5 rolls off more rapidly below 100Hz.
Forgiveness. The OM6 is much less forgiving, as alluded to above, while the OM5 is more suited towards singers with less than stellar mic technique. It’s not a knock, but just remember that singing right up on the OM6 will cause problems.
Deciding which of these you go with depends on your relative stance to the mic. If you’re going to be right up on the mic, the OM5 is your boy. It’s more forgiving of technique, and will reject off axis sound better in close quarters.
If you’re more particular about mic placement, and need something that’s a little more flexible, the OM6 is the way to go. It’s better for vocalists who tend to get a bit more sibilant, and will allow you the freedom to move around more.
