- Acceleration at 500 m/s (much smoother now it's lower than 9000m/s!!)
At 0.3mm layers, I can get 100m/s prints [...]

Can we assume you mean 500 mm/s2, 9000 mm/s2 and 100 mm/s?

Acceleration, while allowing higher speeds, lowers the quality of your corners.

Ah, it has taken RepRap how many years to recognize this simple fact of physics? Higher acceleration means higher forces and as such more printer frame bending. Not to mention a higher risk of step losses (which resulted in many people searching for position encoders / verification methods).
If you get better quality with higher acceleration anyways I'd guess it's due to the fact that extruders don't push out material immediately, but do so a bit delayed. On what "delayed" exactly means, experts debate for quite a while already.

the bottom line people seem to forget also is that we are building printers, not race cars

I used to have an acceleration of 1000m/s2, but have since raised to 4000m/s2 and a bit slower speed, vastly improving my quality.
