I have an E1L that has become my EDC for office days. The standard G2 pouch holds it and an extra 123 battery. The only *2* that I have is the A2, so it's not the comparison that you are looking for, but I really like the E1L. It puts out a lot of light for a 1 battery light, and no need for an extra lamp to carry.
