Multi-finger chords.
Donny this is one of your better posts.
If you study what an organ player is doing with his left hand you will understand why multi-chord finger is the best. In short, there is something happening besides your left hand and the style.

Why?
1-I can add all the extensions of the chord I am playing. Ex. G7-9#5
2-My left hand can feed my right, or my vocal. String section – Brass—or piano. I hate strings in a style – it keeps on moaning and moaning. With my left hand I can control what I need taking the boredom out of the style ---- and it is supporting the solo or vocal.
3-Did you ever want a guitar strumming – well that is my left hand.
4-With my left-hand set to a lower piano sound with after touch – and my right hand is set to piano with or without Ensemble/Chord Harmony I’m a piano player.
5-When a minor chord has its root moving down in half-tones – Am to D7/D9th it is my left hand that covers the change leaving my fight hand free to add what is happening.

Having studied guitar and taught taught guiitar and played guitar since my twenties I was able to transfer what I leaned to the keyboard. If there is any interest I’m up to sharing.

My opinion: One of the best features on a keyboard is the switch that cuts everything but the drums and bass from a style. I get to add the pads I created and my right and LEFT HAND. Good bye boredom!
