With Gestice we tried to make it more secure by syncing the gesture on the pebble with the phone; I'm not sure that other apps provide this syncing functionality. As well, Gestice keeps your screen locked with a PIN in addition to the synced-gesture unlock. This wasn't an easy engineering task -- it took a lot of persistence with with the Android APIs. (The only string attached is that Gestice has to be given a PIN for your lock screen, which it manages for you.)
