Bishop Or Knight?

I couldn't find a post already concerning the matter of whether bishop or knight is more valuable. I think that having one of both is best. My reasoning is because when I play, I prefer King's Indian games where I use one of each to defend the king and my other knight + bishop to mess up pawn structures forcing my opponent to think and use time while I camp out. This works against opponents that can only look ahead a few moves because my king is so defended I don't have to worry about being checkmated until my opponent does something suspicious like develop a queen and rook on the same file. Long story short, which is the best if I choose to sacrifice 2, 3-point pieces for my opponent's 2, 3-point pieces. Do I give away my knights for bishops, bishops for knights, or any combination thereof.

Most granmasters think bishops are a little bit better.

The more open the position becomes, the more valuable the bishop becomes. Since most games becomes really open in the end game, it's almost better to have a (good) bishop.

In your King's Indian structure, even if the bishop is blocked by your own pawns, you would still prefer to have that then a knight on f3/f6. This should inspire you to value this piece more.

Modern theory is that it depends on the position, but that there are more positions where the bishop is better than where the knight is better.

Furthermore, it is said knights gains value in blitz and bullet chess, due to knight is more unpredictable compared to the bishop. It is more easier to fall for forks in time trouble / time scramble.

Blitz / bullet
Hypothesis: knight increase in value as time is nearly depleted, compared to the bishop.

as a general rule i learned that a bishop pair is most of the time superior to a bishop knight or knight knight combination(its about half a pawn advantage to have a bishop pair, of course there are some certain well developed openings who proves this wrong).
if there is no bishop pair available i treat knight and bishop as equal.

Each and every game and each and every position determines the true value of each and every piece... The market is always in flux. Sometimes the darksquare bishop is worth 2 points and othertimes is worth 3 or 4 or 5 points... It is the KING's job to assess the pieces true value and get the most bang for the point. - just my take on piece value.
