Battuss,
May I say I'm quite an expert when it comes to these cases ?
There are many many more aspects than weather and taxes.
How about a warm taxheaven with a murder ratio of 1:500 ?
Or a nice climate, low tax, but a government that collapses and takes all your hard earned money ?
I can give you great advice I normally only give to close friends.
First I will give you some links that will change you point of view completely :
