I kind of think it was. The best argument I think is embodied in Kent Pitman's comments in this usenet thread [1] where he argues that for the Lisp Machine romantics (at least the subset that include him) what they are really referring to is the total integration of the software, and he gives some pretty good examples of the benefits they bring. He freely admits there's not any reason why the experience could not be reproduced on other systems, it's that it hasn't been that is the problem.

I found his two specific examples particularly interesting. Search for

    * Tags Multiple Query Replace From Buffer

and

    * Source Compare

which are how he introduced them. He also describes "One of the most common ways to get a foothold in Genera for debugging" which I find pretty appealing, and still not available in any modern systems.
