What is better??? A queen and a pawn,or two rooks??

If the rooks are connected they are better then the Queen and pawn

Not always, even if the two rooks are connected. If a queen can invade the diagonal and pick up other pawns present, then the queen prevails.

Not quite. Count.

Rook= 5

Queen= 9

5+5=10

10>9

But with skill it is much better, because of harmony.

Sometimes I lose

That's beginner's crap!

Long story short, it depends on the position.  The more open the board is, the better it is for the Rooks.  If the board is filled with pawns and lacks open files, even if connected, the Queen is better.  If they are connected, the Rooks can likely defend, but do little else.  If they are disconnected, the Queen is highly likely to prevail.  In a more open position with fewer pawns, the Queen is unlikely to win, and can even lose if the Rooks are able to dominate and one of Black's pawns is passed (even if he's a pawn down, it's the passed pawn that matters, not the quantity of pawns.

That point system is beginner's garbage.  Once you learn the right way to play the game, generalizations like that baloney will be a thing of the past for you.  I've seen just a Rook beat two minor pieces (without an extra pawn), I've seen Bishop and Knight beat Rook and two extra Pawns.  I've seen a Queen by herself with no extra Pawn beat two Rooks.  I've had two Pawns beat a Bishop or Knight in an endgame.  All of those scenarios see the player with "less material" prevail!

Lesson learned, material count is bogus.

You say it depend on the position.

But look, Metalwarzone didn't specify a position either so I thought it would be better to appropriate to answer in that way.

Queen =  9 Points

Pawn = 1 point.

So basically it's the same points. But in my opinion you can do the rook roller with two rooks but the queen can move anywhere than the rooks. If you have a pawn and want to get another queen the rook will take at one point if you are in check. And if you fork both rooks at the same time you can take one rook. 

I would think most of the time the players would agree a draw (in most positions). King safety comes into play as well. In my experience, I've played a standard game OTB & such a position arose yet after so many queen moves I realized just how strong connected rooks can be so I took the draw.

It depends on the pawns and kings. It may be a draw or a clear win for either side. Or advantage to one side or another without a clear win.

Closed position, I take the queen and pawn. With everything open, I like the rooks.

Yes.  Maybe the rooks are better.

I'd pick queen, though in theory two rooks are usually better. Queen is easier to use imo

Each queen has her own room

Depends on the rest of the material, and whether either king can find shelter.  The 2 rooks are usually better (typically they have better winning chances), but there are a lot of drawn positions in this type of endgame due to the queen's ability to create perpetual check situations.
