Chic, each hinge type is different, and has different reasons to be used or not. On my first turbine plane ( Kangaroo ) the rudders were hinged with Radio South CA large hinges; Hundreds of flights no issues. My BVM planes have a wide variety of hinge types all for the type of surface and or materials they are bonded to. On my std size and 125% Turbinators I have the largest sized Dubro hinges everywhere except for the flaps which are the large Robarts because of how they need to move away from the wing when they lower. All are good, the most important thing is to use the correct adhesive and clean the plastic ones and rough them up before you glue them in.
