It's all a matter of perspective. You have to consider where the respected imager images from and the average conditions and correlate that with when/where you will practice your art. TEC 140 have a less than stellar reputation for imaging (search for blue halos), pun intended.
IMO there's little to be gained from a scope that can theoretically show you more and to experience that on one or two nights a year. Most of us don't live in the desert but the more temperate coastal fringes where conditions for high resolution astro imaging are less than ideal.
I'm not trying to discourage you from the MN190 btw, as I said I'd like one myself if my circumstances were different
but there's a lot to be said for ease of use, even if you need to take a few extra subs to compensate.
What you really need is a spread of scopes to test, in parallel, on a bunch of randomly selected nights through the year. Since you list your location as UK, most of those would probably be cloudy anyway
