A properly prepared joint with a quality epoxy resin is the best. You need to sand both surfaces with 80 grit sandpaper and clean them with acetone. 5,10,15 minute epoxies don't do a very good job quite honestly. A quality bonding epoxy (3M or Hysol) or a reinforced and thickened laminating epoxy will perform better than CA.
If you don't want to prepare the joint and don't want to buy a good resin and the appropriate fillers (cab-o-sill, cotton flock) then use CA.
