I'm not sure if "Won me Over" describes how I feel.
And Don't really foresee being Thrilled with the Final Regulations/Actions that the FDA Takes.
But I see Mr. Zeller as someone who Still Believes that Science, Real Science, should play a Role in Regulations. And that Emotional Hype and Political Agendas shouldn't be the Primary Driving Force with regards to e-Cigarettes/e-Liquids.
If you do a Quick and Dirty Google Search, you can find things that Mr. Zeller has written and Interviews he has given. I have kept upon some of what Mr. Zeller has Said/Done since I learned from Bill G. that he would be in the Position he is at the FDA
I hold Zeller responsible to some extent for the FDA's draft of the deeming regulations, and found what C.V. Phillips says about the role of science therein to be illuminating:
Scientific claims in the FDA deeming regulation (part 1 of ???) | Anti-THR Lies and related topics
I also thought it was noteworthy that Zeller lumped vaping in with other "tobacco products" in his News Hour interview with Judy Woodruff, which was the only video interview that I believe he gave (or has given?) since the introduction of the proposed rule. In fact that was his opening sentence - "tobacco products" kill 400,000 Americans a year.
For some reason, he failed to mention that vaping hasn't yet killed anyone. Although he did go out of his way to single out charger fires, and the poison control center calls. Needless to say, I found all three of those facts noteworthy.
But at the end of the day, I think focusing on one individual may be unilluminating, no matter how much integrity one may attribute to that person. (And I say that because I suspect that you view Zeller as a man of great integrity: someone whom vapers can trust.)

But let me Get Back to something I keep Mentioning but No One seems to think is Pertinent.
Doesn't Margaret Hamburg have something to say about How e-Cigarettes/e-Liquids are Regulated? Why does her name not get Mentioned Much?
What About Sylvia Burwell? Isn't she Zeller's Boss's Boss?
I don't know how much of a role the Commissioners play in each of the divisions. Sylvia Mattews Burwell was the head of OMB when OMB originaly kicked the draft reg.s (also produced under Zeller) back to the CTP. And also when OMB approved the reg.s. Since no one knows what - if any - differences exist between the two versions, it's hard to say much.
And like the FDA, OMB has a lot of moving parts. OIRA is only one.
Again, I prefer not to view at this through the lens of individual personalities. I look at the CTP's actions and proposed actions as if it were a kind of monolith. My perspective would be little different if I thought Mitch Zeller was Jesus Christ, Mahatma Ghandi and Mother Teresa all rolled into one. And the same goes for Burwell and Hamburg.
That said, I can't see Jesus, Ghandi or Mother Teresa as a lobbyist for Glaxo (makers of NRT, who have been well and duly busted in their efforts to influence the EU's TPD). In general, it stinks when a former lobbyist for one industry is put in charge of regulating a competitor.
