If AES 126 is NOT a typo, it is definitely out... but...

If AES 128 was what was meant, there is some argument in security circles as to whether AES 256 is actually STRONGER, although the length of the key suggests that it must be. Most security people I speak with agree that 256 is probably stronger but since none of us has the time to do a 149 trillion year crack, I guess we may never know.

Obviously any version of DES is weaker if you are familiar with the function of that algorithm although the key length may tempt you to believe otherwise 😀

Great question but the explanation does not begin to do justice to the answer.
