DOF H3-h6 questions, chair models, buttkicker and other things, or other brand/type?

I’ve seen it mentioned something along these lines for motion sims and flying, but yet i see many that love the motion rigs, ala vr flight sim guy h2 or others with h3 or other setups so im confused by this (they call it realistic and like real world despite the way it works)…

“Why would you want your motion platform to tilt sideways synchronous to the roll maneuvers of the aircraft? In a coordinated flight there are no lateral forces on the pilot. Why would you want your platform to pitch accordingly to your climb and sink? In an accelerated dive (nose down attitude) the pitch down movement creates the wrong feeling of a decelerating aircraft.”

Seems the opinions are mixed?

back to the h3 setup, im definitely going with the upgraded motors and i cant figure out which seat fits and isnt a fortune
