Which is better in chess openings 'e4' or 'd4' from white ?

Neither are better, but they have differtent outcomes.
d4:A defensive and more positional game and might take longer. Possibly a higher chance of a closed game.
e4: A more faster and swift game, with more exchanges.

Kasparov says ("Kasparov's Curriculum", Chess Life, March 2009):
"...d4 always offers you a variety of options. It doesn't mean that e4 is weak, but it's no accident that leading players are all moving to d4. With e4 there are too many complex problems that White has to solve..."
Now I'm no Kasparov, I've had my share of great games with both moves, and the remark is cryptic for many reasons (the author goes on to suggest that a white player would much rather deal with a Grunfeld or QG than a Petroff or Marshall), but clearly Garry has a slight penchant for the queen pawn. Whatever analysis might have been needed to back up this claim, I'd have to say that both moves are good for lots of reasons, and the subtle differences are not something the average player will gain a tremendous advantage from.
Based on what I've been learning from my study of Bird's Opening (f4), there are all sorts of things you can do to contest the center without directly occupying it. When in doubt, though, Kasparov sure isn't a bad source for some good advice.

Pepsi or Coke?
My guess is that both moves a almost equally good so what you like to play should guide you

Agreed! I wish chess was just as easy for me!

Good point.
I also think d4 is harder to combat against as black than e4. I have alot more fun against e4 regardless of whether I play sicilian, center game or e5.
I have a tougher game against d4 and usually end up playing stonewall defence in a closed game that runs well over 40 moves. Probably because I avoid the opening like the plague. It trully narrows down blacks options, yet I always play e4.
d4 is harder for black during the openi

It depends on your playing style. I always play e4 because I like open positions where there are many opportunities for tactics. I generally dislaike closed positions so I don't play d4 at all.

It's obviously a matter of taste and style of play. I've played d4 most of my life,which is now a bit of awhile,because it tends to be more positional and lead to end games. However, if my opponent opens into a QGA the game can become very open,tactical,and bloody. A Lot of fun. I've played the Trompowsky Attack but for me it didn't have that much variety so I went back to the QG and will probably study and play that the rest of my life. I now play the Tarrasch Defense against d4. I do prefer open games and it leads to a good open game.
Both are good openings, but they are only as good as the player. And you know no two games are the same, so try playing both to see which one suits your style of game.

I tend to prefer d4, although stats currently say white has slightly better chances with e4 (FWIW, given the difference in sample size).

I'd played over 600 games and all white game i'd opened 1.d4,,, 2.Nf3 3.Bf4
I'd learned play chess lately and lose all game i'd played 1.e4,,,then i'd discover that 1.d4,, 2. Bf4 3.Nf3 gaves me more confidence and cotrol over the opening
and now i can do nothing much with 1.e4,,,strange,,,
only a few lower leveled beats me after 1d4,,etc..after i started to blunder,
playing these moves will leave you with no margin for error!
in feel it and still can't improve that cause every opponent is different.
Good to try the Dutch openings, starts also with 1.d4 and i am Dutch, but not a chessman, i only love the game more then women.
The better question is larger. It is what opening you want to play. Answer that question and you will have answered the question about which first move is better. I happen to often enjoy playing the King's Indian Attack or the King's Gambit, so e4 is better for me, but I would never say it's a "better" opening move in some larger sense. Sometimes I like to play the Queen's Gambit, and on those days d4 is better!
Good luck.

The funny thing is, when Kasparov was interviewed on Italian TV last year, at the end of the interview the show host took out a little chessboard and asked, tongue in cheek, "Can you show me a move that will let me win every time?". Kasparov played 1. e4 !
I think e4.
