17mm vs 19mm master brake cylinder, pros and cons? Options

[914 RZ-1]

I need a new M/C. Stock is 17mm, but it seems everyone is selling 19mm. I'll get a firmer pedal and less stroke with the 19mm, correct? Is this good or bad or personal preference?

What are the advantages/disadvantages of both?

Thanks!

19mm - moves more fluid, less pedal travel. Needs more force at the pedal.
17mm - moves less fluid for the same travel. Less force needed at the pedal.
It’s a ratio, you trade travel for pressure.

I personally like a soft, longer travel pedal. Easier for me to modulate and I get more force at the caliper with less force at the pedal.
Lots of people like firm pedal.
