The scopes I have used are in my signature below for your reference, so I am sharing my experience with this range.
Between the 85, 92, 120, 127 mm apertures, I have been able to tell the difference between each of them. Not mindblowing difference, but noticeable difference. I have a 160mm on order as well which I am sure will bring even more difference. There is substantial difference (to me) between the 85/92 class vs the 120/127/130 class. Depending on where you place your expectations, each of these scopes can make you smile when looking at bright targets.
The increased aperture (limited by factors beyond our control, such as seeing and such) allows higher resolution of surface details especially on planets like Jupiter with rich colors & bands, or for studying the details on our moon on high magnification.
For deep-sky, I gave up on refractors and have been using EAA using a RASA 8. The RASA 8 is a fantastic mirror scope - no collimation needed and has a F/2 so my live-stacking for some of the eye candy targets is in the matter of seconds, not minutes or hours. I might try the PVS night vision + refractor combination when traveling -- the NV has been on my radar for while so I've added my name to the wait list as of few weeks ago :fingers crossed:
