I've had mixed results myself. When I first got my Ender 3 I picked up the Creality glass and it was amazing, everything stuck without much effort, and popped loose once the glass cooled down for a few. After a couple years I started wearing out the surface texture so I picked up a new piece from the same seller. Nothing would stick to it no matter what I did (other than hairspray, but I agree -- yuck!) so I finally started experimenting with other plates. The G10 is good stuff and pretty cheap if you're willing to cut it to size yourself, but I still had some issues with it not sticking as good as my original glass. Meanwhile I switched my printer over to a direct drive head which really threw a curveball in my settings so I pretty much had to work everything out from scratch again. I ended up dropping a PEI sticker on top of the G10 and that seems to have solved most of the problems.

That's one of the bad things about the current state of 3D printers -- it's not ALL about the nozzle gap, there are other factors that come into play. I can set my gap in my sleep to within a few hundredths of a mm these days, but the same settings I used with the original head don't work the same with the new one. So if you changed something right before you started having adhesion problems, it likely means you'll have to play with your slicer settings to find what works now. It sucks, but I guess that's the price we pay to be able to make things out of nothing.
