There is no difference at all, concerning "perspective".
And primes? For FF there are really only 14mm primes. The Canon costs a lot and AFs, the Samyang distots a lot and has no AF. There were 17mm primes a decade ago, from Tokina. They are ok-ish from f8 and up. And from Tamron, a bit longer ago even.
Samyang has a 10mm f2.8 MF lens for APS-C.
UWA zooms for APS-C are cheaper and lighter.
