Italian vs Spanish

That's wrong, Ruy Lopez can contain sharp lines like the Marshall, the Italian can be really safe if you want e.g, Giuocco Piano Main line, Giuocco Pianissimo, or Giuocco piano, 4.O-O variation

I like ruy lopez because after nf6 the berlin defence is losing at my level for black because everyone plays bc5 on move 4 or 5. But if the opponent plays a6 the games mostly go into the closed morphy defence which is good for white because most people play c6 against the rosen attack in the the closed morphy.

The Italian game appeals to those who like open, highly tactical games (not that all games are like that). The Lopez appeals to the more positionally minded players who strive for the accumulation of tiny advantages and a winning endgame (not that all games are like that).
I like the Two Knight's Defense when facing the Italian and I like to open the position against the Ruy Lopez.

I don't think any common opening is winning or losing in the opening until you're a GM. Even then really... Ok, super GM. 

hey (batgirl). I've read a few of your articles. i cant remember about what but i remember liking them. i think one was the history of time/clocks on Chess?

Giuocco pianissimo is definitely not "tactical" in fact it is white's choice most of the time, he can chose to play Evans or a positinoal line against Bc4, or he can chose to go Ng5 or d4 against Nf6, but most of the times people play d3 and just positional boring chess, since then I learned to never play e5, I usually would play e5 to try some traps but NEVER EVER I will play e5 again exccept if I can find a way to spice up a boring variation

hence the "(not that all games are like that)"

Oh k @batgirl

Yes, Batgirl is the one who write the very informative history articles!  But not all articles are like that  lol 

Yh she's top blogger deservedly 

chamo is right, the Italian generally only gets tactical if white wants to.

From 1900 to around 1990 the answer would have been clear. Top  players overwhelmingly preferred the Spanish. But since then, Black has perfected some really hard to crack defenses to the Spanish (The Marshall and the Berlin). At the same time, some top players began to experiment with the older, Steinitzian Italian game with 5.d3 instead of 5.d4. Since then, interest in the Italian has exploded--but so has theory! There are a lot of subtle move-order issues in the Italian that can be very confusing. 

Here's another reason:
