/ scarpa vs sportiva boot sizes
I have Nepal Extremes in 44. Couldn't get my feet in a 42, 43 was really tight. 44 with a thick winter sock fits well. Think 43 1/2 would have been the ideal fit.
So I've not got experience with either of the boots mentioned, but I'm an EU40 in La Sportiva Trango Extreme (Women's), and length-wise I'm an EU41 in Scarpa Charmoz (again women's).
I say length-wise, because, as a previous poster said, Scarpa have wider heels which doesn't suit my feet - tried to have them fitted with volume reducers, etc. but still no luck. The heel on the 40 Charmoz fitted ok, but toes were touching the front.
Hope this makes some sort of sense...
