People "usually" suspend their laptop, so that they can continue their work when they open the laptop. OK! Two choices [GNOME]: 1 - Menu -> Shut Down -> Suspend in this case, the gnome-screensaver locks the PC. but the gnome-screensaver is just a "normal process", and it could be killed e.g.: http://securitytube.net/USB-Autorun-attacks-against-Linux-at-Shmoocon-2011-v... or using any method [video was just an example!!].
2 - Menu -> Log out -> Switch user -> Suspend in this case, the GDM [???] protects the user [i mean it locks the PC from other users]
Which one is more secure/safer?
You should consider asking this in the gnome users's group rather than two (or more?) OS groups that happen to use gnome.
There is a third option, hibernation, which you did not mention, but essentially they are all more or less equally secure - they all require login password authentication to resume operation once the computer is "brought back."
