In the old days, the specs for DACs and ADCs were easy to understand, at least after you figured things out, and all the major vendors had app-notes explaining what the parameters meant. There was INL, DNL and a few buzzwords like no-missing-codes and monotonic. Ballpark of 20 years ago, things got much more complicated. A new generation of chips came out targeted at DSP applications. FFT plots started appearing in data sheets. Parameters like ENOB (effective number of bits) became the important ones. On top of that, if you are interested in audio or radar, temperature stability is not an important parameter. -- These are my opinions.
