I can't speak for the GC .84OC or with as much experience as some of the other members but if you ignore the stubble removers (DE89, 34C, Vintage) and start the scale at efficient razors. The GC 84P is a very efficient and smooth razor, JAWS is getting into aggressive but not as aggressive as R41. If you like a more aggressive shave than GC .84P without being as extreme as R41 the JAWS is a happy medium
IMHO
