I prefer using my face as an avatar for marketing that way I never have to start over from scratch building my brand. When other people shut down a business, website, channel, etc. and start something new .. they need a new logo .. which nobody knows so they're starting over from scratch. Use your face and you never have to start over .. just continue building your brand and new additions to it. When you consider how difficult it is to get a new start-up rolling, branding your face seems to make the most sense.
