Go with ALZIP Its free and It works better.
Problem 1-You have to open the unzipper and manually Unzip them.
Problem 2-You have to manualy reorder the files inside.
Problem 3-It does not quit itself-neither does Alzip, but Alzip does not need to do either of the above.
Problem 4-It is not as easy to use as Alzip.
