so what is the best balancing method

Dynamic (moving) balance is clearly superior to static (stationary) balance.
The wider the tire, the the more pronounced the difference becomes.
A tire that is dynamically balanced is automatically statically balanced but a tire that is statically balanced is not necessarily dynamically balanced.
Consider the first sketch that shows a tire with a heavy spot. [We are looking 'down' at the tire through the fender.] The weight tries to turn the tire 'left' but half of a rotation later, it's turning the tire 'right'. There's a similar 'up' and 'down' thing going on.
Note if we added a weight like the second sketch,, the assembly would be statically balanced but the imbalance would actually be far worse.
