I prefer the idea of a narrower FOV, also I'm a bit of a sucker for higher resolution images allowing me to zoom in and really explore the detail.
Are there any inherent issues with the 183 that you've heard of?
My experience with the ASI178 (which is a smaller version of the 183 with the same 2.4 micron BSI pixels) and my Esprit 100 (=550mm) has shown me that I only get better resolution from the smaller pixels on nights of substantially above average seeing. The rest of the time, the 1600 collects signal faster, is easier to calibrate and can always be cropped.

A mate of mine has a 183 mono and I’ve seen some promising results from it, but the amp glow is a little shocking (especially at high gain and/or longer exposures) and requires more care to calibrate out.
