There should not be any speed difference between the two. I use Nero and clonecd, like most people. easy cd creator is just fine for basic burning. Only stuff like a few data files to a cd, or music burning I guess, but I have not used ez creator with audio cds before. Nero is supposed to be able to copy more cd's than ez cd creator can. I use nero because it is easy to use and has more features, too, such as overburning. I don't think I have ever used any of those extra features, though.
