The wiki section on shields should have information on the stats for all shields along all upgrade paths, making it easy for you to take a gander and compare shields.
For example, comparing the BKS to the Fire Effigy Shield +10.
The BKS has about 11% more fire res than the Effigy, but the Effigy has more magic defense and an outstandingly good lightning defense, giving very balanced resistances all around. However, it also has less than 100% phys res and has low stability, so it comes down to how you like your shields to perform
