Thermocouple Accuracy and Noise?

Main Question or Discussion Point

I'm looking to use the MAX31855 thermocouple-to-digital converter, to measure temperatures in the range of 0-350C. According to the manufacturer, the ADC inside the chip is identical for every different type of thermocouple, just a different sensitivity is programmed in depending on the type of thermocouple you want to use. So, each chip, regardless of thermocouple type, outputs at a 0.25C resolution.

Therefore, since every type of thermocouple that the chip is trimmed for will read my range, is there any inherent advantage to one over another (K, J, N, T, S, R, and E)?

Specifically, are any (on average) more accurate than another? Do any of them have less inherent noise? Are there any advantages to one over another? Thanks!
