really dont know what you want. are you asking which public profile is the best for farming ore and herbs for profit? none of them, unless you really dont care to lose your account. the past year gatherbuddy has gotten very dangerous. using a public profile is not a very good idea. most people who are still using gatherbuddy on a daily basis use private profiles they buy or create themselves.
as stated above, rndbuddy is a good option. totally random created profiles on the fly is a pretty sweet deal. although i really dont care for the setup. personally i use profilechanger plugin. i went to roboto's website and created 12 random jade forest profiles and setup the plugin to run 5-11 minutes random profiles. stop when bags are full, or the profile changer plugin runs out of profiles.
but hey, its my tinfoil hat, ill wear it if i want
