At the end of the day this is just terminology and nomenclature. The 4x mount moves...barely. Just as the TG mounts move...barely.
So little that the feedback felt by the driver is enough to rattle your fillings out, which is what the OP doesn't want.
My feedback comes from a desert racing perspective. And (semi) solid mounting half the drivetrain puts all the dampening on the non semi-solid mounting parts...which rips the rubber apart in spirited offroading. I can't speak for DD or mall crawling, but I started with only the 4x only and ended up with a torn engine mount on the torque side and a bent perch on the non-torque side. Carry on with whatever it is you want to do, just providing my input on what's happened on my truck.
