From "SYSTEMVERILOG FOR VERIFICATION.A Guide to Learning the Testbench Language Features.":
" If you run the same test 50 times, each with a unique seed, you will get 50 different sets of stimuli. Running with multiple seeds broadens the coverage of your test and leverages your work. "

If you need only one set - use constant seed.
Else use unique seed.
