but why do you want to equalise when playing the King's Indian? your main aim should be to seek counterchances (otherwise it's a strange idea to play a KID), not that this is always so easy...

It's indeed my intention , as well that of Houdini , with an eval steady at 0,04 at depth 34 (running my engine 8 hours )
I did not test further yet , but equalizing as soon as move 6 is a guarantee of soundness

I understand very well that , OTB , a player who has not specally worked this line chooses to transpose to well-known variations , but I am a CC player , and I look for ultimate truth
As for me , I analyzed 5..c5 at once  , and it seems that Black equalizes at once
But I could not find in my CC DB any game to confirm it
It is similar to the Pirc between Spasski and Fisher in their world match
I am not fully convinced by 5..Ng4 6 Bc1 c5 7 dxc5 dxc5 8 Qxd8+ Kxd8 : in KID , I don't like exchange Queens so early , nor lose right to castle
Matter of taste : I dislike the "Berlin Wall"

I think the reason for 5.Be3's lack of popularity is 5...Ng4, but when I looked at this a couple of years ago it wasn't as easy for Black to equalise after 6.Bg5 h6 7.Bc1 e5 8.d5 as theory suggests. That said, White seems to be able to fight for an advantage with almost anything against the King's Indian these days, at least until Kotronias's second KID book is published.
