Kharma Ceramique 3.1 vs 3.2 CRM

What does the 3.1 CE give up comparing to the 3.2CRM. Is the Revelator tweeter better than the Focal tweeter for strings and voices?

I listen to classicals (80% chamber & 20% orchestral), jazz & pop. Rarely any rock material. Is it worthwhile to go for the 2.1 (extra driver vs a more complex XO)?

Thanks guys
