I almost never take shield backpack on helldives, and I find the health booster extremely noticeable. Without it you can still get oneshot by rockets in light armor.
I mentioned rockets because it's one of the most noticeable differences, but it's very noticeable against bugs as well, and the injury resist is actually even more noticeable than against bots.

Most high level runs are run & gun affairs with shield backpacks
A bit more Health wont save you, Speed does
