Take a good compromise, go for 26psi.

I tried low pressures and high pressures and for me 26 works well.
At 22 psi I get the feeling of an unstable drive and 28psi provides a bumpy ride.

You have to find out your personal comfort zone.
Not so complicated to change tyre pressure at any petrol station.
