Everyone seems to have something that works for them, that they swear by, and nothing else works. I suspect it’s because 3d printing has a bunch of variables across specific printers and slicer setups, and that different methods work best with different combinations of those variables. Things like bed temp, print speed, extrusion temp, cooling fans, etc etc.
Blue tape works well for me, glue sticks work OK for me, never tried hairspray, occasionally I can get just plain glass to work but why both, I just keeps lots of rolls of 2" wide blue tape around, works great.
If I print with a raft I can have a much wider latitude of build surfaces, but it also takes longer.
