So I made my vote for Belize, since it is very cheap and fast to incorporate there, if you just need a holding company or a simple trading company Belize is where to go for a company formation.
You should have included Cyprus even if it isn't a real offshore jurisdiction then it is still a low tax country.
Anyway, I voted for the seychelles since we also have a holding company there to protect our assets and to be the paramount company for the rest of our group.
Seychelles is very easy to incorporate and it can like Belize be done very fast, actually we had our read-made seychelles company docs within 2 hours...
Well, you should have made this poll to be multible choice.... Many of the offshore jurisdictions you listed above are great places for your offshore company.
