My guess is that you really have to know what the load is on the cylinder before you can compare...if the cylinders don't have to do any work, then sure, the small one will fire more quickly. If they both have to push the short end of a long lever that has to lift a 10 pound ball on the other end, then the 3/4" bore cylinder with 60 psi applied to it will just sit there, while the larger bore cylinder might actually make something happen, slow though it may be.

As sometimes happens, there is not enough information here to give a good answer to the original question
