Drop Springs and shocks questions

[Asshat]

It’s been a minute since I’ve been on here - still have the same truck. Had a question regarding 3” drop springs and shocks.
I heard from one individual that 3” drop springs are not the way to go, they cause the truck to bottom out. What he said was, When they compress while driving and suspension loads/unloads. they are able to move in the pockets.

Is this true?

Are all drop springs basically the same? As far as quality and getting a smooth ride?
Do I need shorter shocks for 2 or 3 inch drop springs?
Is there a superior brand of shocks and/or springs available to achieve better ride quality?

My truck is a 63, however, the front clip is out of a 1974 C20.
