I still learned "standard Latin cursive" in school, which was more or less the direct successor to Sütterlin.

They are remarkably different. Especially the lower-case letters, where around half are completely unrecognizable. Cursive Latin is arguably closer to cursive Greek than to Sütterlin.

Some lower-case letters straight changed meaning during the Sütterlin->Latin transition. d->v, e->n, ect.
