What's the correct way?
- The first one("have") sounds me the correct, but I can't explain why.

The world better has strong leader
What's the correct way?
If you're looking for an idiomatic version, neither, but your first option is closer to being grammatical.
You should use, and maybe unintentionally are using "had better".
"had better" is what Quirk et al. call a modal idiom. I checked, and CamGEL considers it as idiom-like as well. That means it's normally colloquially fixed and you don't usually see different inflections, such as has better, unless perhaps for humorous effect.
So the grammatical sentence is
The world had better have a strong leader.
However, it's also common in informal registers for the had to be dropped, resulting in
The world better have a strong leader.
As a side note, your main verb, have, sounds a bit odd. Consider if "find" would be more appropriate for your sentence.
c.f.
You better run!
