I can only comment on the larger chip size required for full disk lunar/ solar.
The ASI 174MM is a compromise and really needs longer fl (>1000mm) to compensate for the pixel size.... I didn't experience any issues with the ASI 174 other than Newton Rings in Ha solar - fixed with the T2 tilter.
The ASI 183 looks good on paper BUT it has been withdrawn by ZWO for narrowband solar imaging (""Technical issues"") I ended up with the ASI 1600 to get the smaller pixels and good coverage.
Used with ROI it is capable of good frame rates.
Just my 2c
I use FireCapture with all my fast frame cameras....
