depends on what type of clients do you want? I had the same dilemma, went with personal branding for everything - I prefer clients I can form personal bonds with and they prefer that too. I was never attracted to agency type work, most of my clients have a "no agency" preference as well. I think that's quite common in the small to medium sized startups area. After thinking about it from this angle, it was a no brainer for me. Personal brands also tend to do better lately than impersonal companie? (when I work with others I just credit them) btw Chris Do is great at breaking this down and he has a lot of resources on this topic
