I bought a $20.00 finned and fanned 1.75mm end with a .4mm nozzle (actually .35mm) from Aliexpress and could not be happier. The best thing I did was add a piece of aluminum tubing to keep the filament straight between the Hob Gear and entry hole. No more flex in the filament as head moves left and right eliminateing filament pushout.

Sorry, that is not correct. Depending on the nozzle shape the print can be quite different. Flat nozzles tend to easily brint plane surfaces with little calibration effort, while sharp tipped nozzles require better calbration but deliver better precision and bridges. Most hotends are of the flatter kind.Quote

The hot end is either going to work or it isn't. You won't see any difference in print quality from one to another.

You may see a difference in print quality depending on the nozzle size, layer height, and the object you're printing.
If you have a hot-end that works and you're looking to improve print quality, look elsewhere. Print quality is affected by things like frame and guide rail flex, sloppy bearings, printer speed and acceleration settings, printer calibration, and slicer settings. Notice the last few items in the list are free. Optimize those before you start spending money on new printer parts.

All those things speak to reliability, not print quality, which is what the OP was asking about. I suppose actually finishing a print can be considered a quality issue, but for me print quality is about the surface finish, and accuracy of size and shape. None of those are affected much by the hot end. I think the drive mechanism that pushes the filament into the hot end is of much more importance to print quality, at least by my definition.

Have you compared the quality of using various hot ends?

Until someone actually runs a well-controlled test, all arguments on either side are just blowing smoke.
