SM 300M Chronograph mid ´90 movements?

Howdy folks

I´m lookin for a daily wearer and I kinda like the SM´s better that Speedys. I´ve been mostly lurking on the vintage side trying to learn but mostly learning how little do I really know about Omegas...

My question is that what movements has Omega used from ´95 to 2000 in SM 300M Chronographs. I´m currently checking two options; one with ETA 7750 / 1164 and another with ETA 7750/1154. Could you give some quidance what movements have been used and are there some issues or preferences with any of them.
