I don't see any particular "selling points" that can make using SPICE 3f5 on an old Amiga preferable to an improved SPICE version and/or a more powerful newer computer (not necessarily a very advanced SPICE or a contemporary computer).
All the article demonstrates is the practicality of analog design on the Amiga back in the day, which is only relevant now in unlikely and catastrophic forced retrocomputing scenarios; other Amiga software, such as exquisite graphics editors, has retained much more of its usefulness.
