ASI183 or???

Doing the maths for my 450mm focal length setup and typically good seeing, it would seem between 2 and 3 uM pixel size would be ideal. This somewhat limits choices, yet the ASI183 at 2.4uM comes to mind.

I currently use an 8300 chip camera with 5.45uM pixels and not been unhappy but will a 2.4uM sensory deliver sharper results? (FSQ85 - 450mm - f/5.3. Seeing here is typically 2 FWHM or less)

EDIT: just to re-iterate, I have ZERO issues with guiding, the mount or the scope. ZERO. Perhaps my focusing could be better (hand focused with a Bahtinov) but this is not what I am asking about.
