BETTER:
The sign for better comes out to the right a bit.
BEST:
Notice that the sign for BEST makes a much bigger movement. It actually
dips down a bit for emphasis prior to moving "way up." The
more you exaggerate this sign, the more your are emphasizing how much better
something is than the others.
