Yeah, Ceekay put it well there. Here is an example of this with two clippers. The first one is pretty traditional clipper shielding.
A ship builder, outfitting and comparison tool for Elite Dangerous
s.orbis.zone
1100+ shield absolute strength, 1600 to 2800 after resistances. Regen is 4,4/s
Here is a clipper with some guardian shield reinforcements with focus on getting a fast charging resistance build.

About the same 1100+ absolute shield strength, 2600+ to 3700+ after resistances. Regen is 5,1/s
The second one creates a lot better basis for a PvE combat ship.
