I tried the 1 and .3 micron lapping film yesterday. Great edge and finish.
I don’t have a definitive answer to your question. It seems logical to suggest that grit is grit and that if you get there with ceramics or whatever then the result will be the same. However when you start talking about stones/films and strops then there are variables such as surface flexibility and pliability to take into account.
I too would be interested in an answer.
