they both work about the same, which is really positive engagement and disconnect.
I bought a Hirame chuck and the Silca copy to compare. <cough cough> Oh, excuse me for being so bold!
Both are great, I prefer the Hirame, but only by a fraction. I bought three rubber washers when I got the Hirame, I expect them to outlast the user. As I said in the other recent thread, I wish I'd bought one twenty years ago.
Further, to me, the chuck is what makes the pump. A great chuck will make any pump a pleasure to use, but a chuck that is a chore to use will make any pump seem mediocre.
Good luck.
