really...
Which is better KG or QG

Yeah the King's Gambit is not played in Vote Chess here at all. Where you can find several Queen's Gambit games. Plus have to see more different defense also. If they take the c4 pawn it can be some serious problems added in white can get the pawn back.
Playing it requires better timing in the moves against these various varations. Even the GM argue about the placement of certain pieces in the Queen Gambit and it changes like every 10 years.

Kings gambit has lost most of its popularity in the last century. Several XIX century great players successfully used it as their major option as white, but through the XX Century these kind of players became rare.
The overhelming majority of Masters and skilled amateurs agree that 2.c4 is the best move after 1.d4 d5. However, the number of those who would say 2.f4 is the best option after 1.e4 e5 is way smaller. Look at databases and you will see the King's Gambit is no match to 2.Nf3 in terms of popularity.
Modern theory favours the QG, while the KG seems to have no much place on top games.
If you are not a professional, however, you shouldn't care much for this, specially if your opponents have no book knowledge after move 4 of any opening.

The bishop's gambit beats both the Queen's 'Gambit' and the King's Gambit: 1.e4,e5 2.Ba6!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

You cannot compare two totally different openings, they are the opposite of each other, approximately.
