I have nothing against either means of carry. Both have a time and place. I think the main thing is your actions while carrying. This will determine how people perceive you more than anything.
If you are carrying concealed, but constantly touching or adjusting your firearm you may as well open carry as you have made it obvious you are carrying.
If you are open carrying, just be sure to be extra watchful, polite, and friendly. As I have several very cute holsters there are times I open carry because I don't feel like going through the mess of trying to conceal as a woman (as it is 150% harder than trying to conceal as a guy). I have actually found it to be very positive most of the time. Granted, most are not overly intimidated by the girl with a matching purple belt, holster, and mag pouch set with hearts and butterflies on it.
I have actually changed the minds of a few people that were anti gun thinking all gun owners were testosterone laden jerks out to show the world who is boss. I have had far more approach me and talk with me leaving with a very positive feel, than I have people who gave me dirty looks and got bent out of shape with me carrying.
Though I do live in AZ in an area where it is not that uncommon to see someone carrying.
