Belize and Seychelles are both good options. I think you'll be happy no matter which way you go.
As for best jurisdiction, I would say it depends on the needs. there's no one size fits all. I would say something like Panama for Personal tax residency, Seychelles for foundations & tied with Belize for IBC, Mauritius maybe for banking. But this just suits my needs. I don't need access to the EU for example.
