It's quite an individual thing. Every wearer has his own preferred adhesive and his own pattern of where he puts the tape and/or glue. You need to experiment to find out what works and feels good for you. Tape gives a stronger hold and is less messy to deal with, but glue shows less and you can't feel it. The conventional solution is tape around the back and sides, glue for the hairline. If you are not exposing your hairline you could use tape all the way around. Conversely, some guys use an all glue attachment, often because they are dating and they don't want a girl feeling an edge.
