Changing the sampling doesn't make a huge difference IMHO.
A large aperture, apart from higher resolution and capturing more flux, tends to make things positionally stable, but the rub is, stars are often fuzz-balls unless the seeing is excellent.
Regardless of the optics, excellent tracking (i.e. rock-solid mount with seeing limited tracking accuracy) pays the best dividends IMHO. The fewer guiding corrections the better. This is no small ask particularly when you start imaging say at 3400mm (e.g. my RC16's native FL).
A guiding correction after all is a measure of blur....fewer and smaller corrections means less blur, hence higher resolution sub frames, which is what you want for galaxy images.
Hope that makes sense
