Eclipse on MacOS X

Wonder which of the available downloads from eclipse.org is right for you?

1. Mac Carbon 32bit
2. Mac Cocoa 32bit
3. Mac Cocoa 64bit

For my Snow Leopard, i chose #3 since Java that comes with the MacOS is 64bit but you need to tweak settings since it consumes memory that it's 32bit counterpart.
