There is no simple answer to your question. Whether to use X-Y, NOS, DIN, ORTF, AB etc. does not depend so much on the particular mics, but on the particular situation. If the mics are close to the performers, I've found the wider spaced configurations (NOS, AB30, AB60, AB120) have that "hole-in-the-middle" sound, at least to my ears. On the other hand, if you are far away, XY can sound almost mono. Don't be surprised that the AB technique works with cardioids; AB works with any microphone polar pattern, and you can use the polar pattern to reduce unwanted noise or reverberation.
It seems that you are considering NOS and DIN the same technique. DIN has 90 degree mics spaced 20 cm apart, whereas NOS has the mics space 30 cm apart. That 10 cm does make a difference, particularly if you a close to the performers.
Don't worry about what technique to use at first. Tape as much as you can, take notes (mic configuration, distance from stage, width of performers, hall size, etc) and/or take pictures, listen, and then revise. After a while you'll be able to listen to the performers in a room and know what technique will probably give you the sound you want.
