Actually I am not particularly in love with the PPB. I rarely if ever use them. So few people use standard shields because of the threat of PPB's that they have lost their real edge IMHO. Typically I will research DUCs to the limit and then switch over to APB's. Although that's simply habit. There are others that work just fine.

This leaves you vulnerable to mid-game attacks. The amount of research you save by not getting PPBs is trivial, and your opponent can use Shield V's to great effect.
If you aren't putting shields on your ships, you are even in bigger trouble, as you make yourself vulnerable to ship capture and engine destroyers.
