Dose it matter about the size of the sealing face compared to the size of the piston?

eg What is better, a 50mm sealing face housed in a 90mm Tee or a 63mm Tee?
If your getting chased off a police dog, try not to run through a tunnel then onto a small see-saw then through a ring of fire. They are trained for that!

It doesn't really matter. In one of t hem you just have more space to vent which makes it slower unless you use a bigger vent.

Model it in GGDT.

I modeled it, and it appears that the 63mm tee would work better.
