Both watches are based on the ETA 7750.
The 1164 is a fairly standard version of the 7750 with a few tweaks to things like the shape of some bridges. Robust, reliable, and in my experience servicing them (and really any 7750) very accurate.
The 3330 is also 7750 based, but has the added features of a column wheel for switching the chronograph on and off, instead of a cam like the 1164 has. In addition it has the 3 level co-axial escapement, which is "more reliable" than the 2 level co-axials are.
Both watches have a beat rate of 28,800 A/h, so there will be no difference in how the hand moves between them.
Hope this helps.
Cheers, Al
