Digitizing can be in two modes:
In both modes, for options that require an enclosed polygon, the program will automatically close the area.
Digitizing mode is set on Printer/Hardware tab of options form. You can also change mode by right clicking on the map while digitizing.
The "better" selection mode depends on the project, and personal preferences (hand-eye coordination varies among people). Digitization will probably be best with a mouse, and not the trackpad on a laptop.
These same modes apply in Google Earth and other programs.
