i dont know if it is useless.
maybe he just got the game and want some advice on what are advantages and disadvantages or something like that.
but i do agree with ArtemisChimera, play them both, read the guides for them both to know how to play them and then see what you like best.
i would also recommend you try all civs, or at least 1 from each category and find the playing style that suits you best, and then choose and perfect with the one you like.
personally i really like playing egypt isis or set, but i also like playing zeus or hades once and a while.
but greek are the most like aok civs, where you have a lot more to learn if you play with egypt or norse.
