Dave,
They are different modules. Either might have either AD9850 or AD9851 DDS chips. See the attached file. The file also shows an adapter board that can be used when needed. The modules are becoming rather expensive particularly the Type I (three rows of seven pins).

A quick word of warning,

There is SoftwareControledHamRadio.io group who have an Antennae
Analyser that uses the same modules but who have numbered them oppositely.

Yes. I noted that some sites disagree on which is a Type I or Type II in the attached PDF.

And the "Type 1" "Type 2" designation is just someone's arbitrary designation, not an "official" one you will find on any of the sites selling the modules.

No they are different in layout and pin arrangement . Same set of chips .
