They are both pretty much the same except for these differences:

Unlike bacteria, archaea cell walls do not contain peptidoglycan.

Archaea have different membrane lipid bonding compared to Bacteria and Eucarya.
   - Archaea membrane lipids have ether bonds instead of ester bonds

There are genetic differences.

Archaea have different metabolic pathways.
   - Archaea do not use glycolysis pathway to break down glucose
