Bigger ferrite beads are better? (more attenuative)

Hi
Both of these ferrite beads are 120R at 100MHz...

0402 ferrite bead:

0603 ferrite bead:

Would you agree that the 0603 size bead is better?, ......because having a longer distance between its terminals, it means less radiated emissions will be able to "jump over it" (couple round it, instead of going through it and getting attenuated)
