I don't know the difference between the 2 but will say our school used Everyday math when my oldest started school. It was awful for him. It would take us hours to do his math homework, this was just basic adding single and double digit numbers. The way Everyday math teaches isn't the right way for him. I am not sure what the use now because DS2 and DS3 don't bring home a lot of homework but I know it isn't everyday math. Now that my oldest is in 6th grade and not doing the simple problems anymore it is so much easier. Good Luck with your decision.
ETA here is how they teach double digit addition
