Adding my 0.02, you'd can do some tests on your box and, as others have said, make your mind based on what is cheaper for you: disk space or CPU.
Original random.out is about 7MB:
$ time gzip random.out
real 0m7.231s user 0m6.650s sys 0m0.540s $ ls -l random.out.gz -rw-r--r-- 1 owner users 39641 Jan 22 11:39 random.out.gz
$ time compress random.out
$ ls -l random.out.Z
-rw-r--r-- 1 owner users 386673 Jan 22 11:39 random.out.Z
