Hard question to answer guys.
How long is a piece of string?
I personally went with an AT PRO.
My reasons... I'm not doing any gold hunting any time soon but it will soothe the lust for treasure in local parks, beaches etc.
I believe it's a good machine for the $$
When I do go gold hunting I'll want a more gold specific, and more expensive detector.
It really is a personal choice.
You need to consider many things, budget, uses etc etc.
No one can tell you the best machine for you.
My thoughts are research research research.
Read as much as possible. Everyone has a different opinion.
It seems obvious the 5000 is the ducks nuts as a gold machine.
Do you want to spend that much?
I can't justify it when it may be many months before I get near a gold field.
Hope this is some help.
