I don't think there is anything more valuable than actually knowing what you like, or don't like—especially in today's world of opinions. Be it cinematography or wine tasting.
For the record, we might want to underline that there is nothing inherent to Full Frame per se. You could create this looks with S35 too. But it might be that FF makes things a bit more effortless, depending on what you're looking for and real world constraints.
You can only start to recreate it on the end of the wider lenses. (It's much easier mid to telephoto.)
No 14mm f/1.4 or 16mm f/2.8 full-frame look available on S35, but stopping down the lens or using an E-mount camera with a SpeedBooster could bring you closer to it if that's what you're going for.

To me this is where full frame really shines - shallow close to subject wides where you can still feel the background but there's that extra layer of separation that makes you feel closer to the subject, just beautiful:
That is what many see as the "full-frame look" because of the wider shallow DOF. It's indeed awesome.
