Direct opposite for me, grub screws do not cut the wire but phillips screws do..
I like grub as well they stay seated and can be tightened better.. Most atomizer modders move to grubs and it is because of the conical shape they rarely slice the wire off but can if atomizer is really built badly. The screws flat shape make a scissor action in a lot of atomizers..
Agree 100% LOVE grub screws
