I'll let you think that.  I, personally, think that it's by prefrence.  I have played against people that have a realy agressive e4 and I have played against people that have a realy agressive d4.  Does it realy make a difference which one you use?  I think not.

still e4.

Many players are being rather assuming here, and believe that 1.e4 is best without even having looked at playing 1.d4 in their life. Chess players are usually taught when they begin to play 1.e4 so they get the chance to play cheap tricks on f2 so they stay interested in chess, and when they get stronger they are just too stubborn to move on to alternatives. They're just too narrow-minded.

Having played 10 of the 20 first moves in tournament competition (b3, b4, c4, d4, e4, f4, g3, g4, Nc3, and Nf3), and after having gone thru many databases, I can safely say that 1.d4 or other moves like 1.c4 or 1.Nf3 that eventually transpose to 1.d4 (like 1.Nf3 d5 2.d4 Nf6 3.c4 e6 4.g3 or 1.c4 Nf6 2.Nc3 g6 3.e4 d6 4.d4 Bg7, just to name a couple) are the best.  1.d4 beats 1.e4 by a full 2% across millions of games.  Pretty strong argument AGAINST 1.e4.

They are the same. Personally e4 is better positionally but d4 has the surprise effect

1.d4 is not a surprise. It's one of the main moves!

My computer screen laughed so hard I had to google-translate it into a language it doesn't know to have a readable image.

1.d4 may be better practically, as it is very easy for White to fall asleep and lose on time in a Ruy Lopez.

e4 still,hhehhehehehe
