My experience with the H2N is good, especially as you can record 4 channels. I don't record choirs but I would guess you would have the same issues with any single microphone point. The ballance is what it is in that situation. If you have a H2N then you have the time to experiment durng choir practice. My approach might be to move the recorder around and see which is the best position, it is not always obvious with walls and their absorbancy. Go for the maximum in sample rate, and use WAV, which may be the only format available in 4 channel.

It is a good little recorder, a fair repertoire of features, and the only con is if you hand-hold. The battery cover can make a noise if squeezed. I put it on a camera tripod sometimes.
