Sure is neat, especially the second one in color.
As a space shuttle child, I didnt know much of any different than the shuttle. Looking at its video, I cant say that it leaps off any faster/slower really.. I dont think...

But why? The shuttle orbiter's gross liftoff weight is 240k lbm. The Apollo combined command and service module seems to be 67k lbm. Sure seems that the shuttle would need more thrust and thus shake the earth more. Is it not so because of a different rocket design? Different fuel?
Each SRB used on the Shuttle produces almost twice as much thrust as one F-1 engine. Two SRB combined with the engines on the Shuttle itself produce more lift-off thrust than the Saturn V.
The difference in sound and feel with the Saturn V is attributable to the difference between a liquid rocket engine and a solid rocket motor. The F-1 produces extremely high amplitude, low and mid frequency noise. It's a loud but deep, deep rumble that you feel as much as hear. The SRBs produce a higher frequency noise, and because of the solid propellant the sound is completely different.
As for the lift-off speed, it is quite different. The Shuttle is much faster. My dad flew down to the Cape to witness the first Shuttle launch. I couldn't get away so I watched it on TV. He was in the VIP viewing area with my mother, I remember talking to him on the phone and commenting on how fast the Shuttle appeared to leave the pad and he agreed, saying that once those boosters lit the thing just shot off the pad, not easing off and gradually gaining speed like the Saturn V.
