I'm quite sure this a meaningful difference between the various colorimeter devices. Some RIP vendors (e.g. Colorgate) strongly advice you to not mix different types of colorimeters between initial linearization, profiling and further re-linearization, even if we are talking about ES-1000/ES-2000.
In daily usage, I often have the same workflow as ColorMeBob described: Profile was created using an iSis XL and re-linearization is done with an ES-2000 although even KM nowadays suggests using the same measurement device for every step.
