This paper by Koopman and Chakravarty looks at several measures of CRC performance, describing the measures and the results for many polynomials. In short, the definition of a "good" polynomial depends on the length of the message it is being applied to, which varies by application. The main measures are the Hamming distance, which is the minimum number of bits in the message that you would have to change to get back to the same CRC, and the performance at a prescribed low bit error rate.
