It looks more consistent with new design language.
I didn't like the old beachball design and I don't like the new one. It looks completly out of place - whole OS is grayish (windows etc.) and beachball is colorful. There's no other place in whole OS that is so colorful.
I don't know how anyone can consider it good representation for heavy background task that must finish before you continue.
EDIT: I'd prefer they rather fix Finder so it doesn't completly hang up and force me to restart Mac when LAN connection hangs up during file transfer or listing catalogue.
