I have the full set of MakerGear nozzles. They work well. The MakerGear extrusion diameter values (extrusion into free air) are quite accurate. Obviously, extrusion onto a build surface and resulting line widths are a different matter.
Mostly I use the .50 mm nozzle, because I print a lot of ABS. The 0.25 is only useful for PLA and I find the 0.35 to be extremely marginal for ABS with the stock UM filament feeder.
Using a simple test case, I swept Cura across my nozzle sizes and a little more. Cura gcode output was invariant within each of these regions:
???-.20
.21-.24
.25-.30
.31-.40
.41-.79
.79-???
So obviously Cura is just using the nozzle size setting to determine a reasonable range of extrusion rates. If your setting is in the right ball park, the results should be valid.
After a solid year of printing with the V1 hotend and nozzle, I finally destroyed the nozzle during disassembly. Because I'm in the USA and a cheapskate, I ordered nozzles from MakerGear. I purchased a .35mm and a .75mm nozzle. On their description page, it says the 0.35mm nozzle actually extrudes at 0.43mm. It says nothing about the 0.75mm nozzle. I know that this is influenced by die swell but what parameter is the "nozzle width" setting is Cura actually expecting?

Im pretty sure it is the diameter of the smallest part of the opening of the nozzle.
