when you say GG .84, all GC .84P (SB), GC JAWS and CG OC are .84 blade gap
when you mean better shave what is your criteria? do you want blade feel, more efficiency?
.84 P SB is smoothest of the lot and a milder than both OC versions with Jaws having the most blade feel but also the most efficient
Timeless is smoother than the .84 Jaws but a tad less efficient
If i were to pick between the timeless 95 SB and all GC mentioned above, and cost was not an issue it would be the timeless without doubt
If cost is an issue I would go the GC, which version depends on what your after
