"Better" for what?
"Just Mac" is "Best"...
Unless you need Windows for some reason.
Then "BootCamp" is "Best" for Lowest Cost and Best Performance.
But Parallels and Fusion have a place too. They're "Best" for convenience and usability.
"Better", "Best" are such tricky, vague concepts.
Why not ask what it is that you want to do? Or MRoogle it!
Have Fun,
Keri
