Please note, I post mostly men's shoes but all these shoes are available in women's model's as well.
The Essential Comparisons:
The biggest difference between Asics and New Balance are the Asics Gel sole and the New Balance Abzorbs Foam sole technologies. Asics Gel soles give their shoes a plush gel cushion making them soft in sensation. New Balance Abzorbs Foam also cushions well using a foam technology that is equally as effective but not gel like. Depending on your activity you may find that you like one over the other. I simply find them different and they both do a pretty good job.
Upper materials are also somewhat different between the two manufacturers. Asics typically use soft stretcheable mesh uppers in most of their shoes giving them a snug feeling as the material surrounds the foot. This gives them the snug and comfortable feeling to their shoes that they are known for and that many like. Asics also uses something called Ahar Heel Plugs which supposedly absorb shock from heel strikes and less prone to quick wear.
New Balance tends to use lighter materials in the uppers but just as tough and breathable. Although they don't tout a special heel plug the shoes are just as effective. New Balance shoes tend to feel more like a runner's shoe as they are different from the insulated feeling of most Asics. Also, it seems in most cases that Asics technology and materials in the more advanced Asics running shoes are just a tad heavier compared to New Balance of the similar models.

While Asics and New Balance may be your first choices for running shoes keep in mind there are other brands such as Saucony, Brooks, Nike and Reebok. A shoe that is comfortable and doesn't hurt you during activities is a good shoe but if you're looking for performance I recommend moving away from the heavier, typical shoes to newer, lighter technologies.

The New Balance equivalent to the above is the new 2011 New Balance 1226, focusing on good foot support and arch support. The New Balance Abzorbs Foam is somewhat lighter than Asics Gel technology. What gets me excited for New Balance are their newer lines of shoes, the Minimus for minimalists and NB890s for those who are not ready to go minimal but want something close with just as much cushioning but lighter than a typical running shoe.
