First of all, you are comparing two different product. AVEVA System Platform is orchestration platform between IT and OT. Ignition is a HMI. In AVEVA we have multiple HMI and SCADA solutions.Like AVEVA EDGE, AVEVA Intouch, Plant SCADA etc.
You can definitely compare System platform as its also a SCADA and OT/IT platform integration piece which is similar to Ignition perspective which is also a IT, OT integration piece and a SCADA, although different technologies they solve the same problem, hence it would be good to see whats better in which category
