I use a Sharpstar CF-80 (500mm at f6.25) guided on a HEQ5 Pro.
I'm beginning to understand the basics around under/over-sampling and from what I can gather the 183MM seems more versatile for my set up, sampling well with average to good seeing, but also having the ability to bin 2x2 when seeing is below average. Is this correct?
My reservations are that I'm yet to find a forum post on any site where everyone isn't praising the 1600MM over anything else around this price range?
I don't have plans to add any more scopes to my gear, at least not for a couple of years yet. So as far as FOV concerns, I'm actually happier with the narrower FOV on the 183 than the 1600.

I have an ASI183MM pro that I chose mainly because of its very high quantum efficiency. Admittedly I am using it for spectroscopy and not pretty pictures but it is a very capable camera. See here

It is in french but you can google translate it with good results.
Here is a test of the 1600
