One major difference, assuming you've got full platform support(should be the case on any server or workstation that isn't an utter joke; but can be a problem with some desktop boards that 'support' ECC in the sense that AMD didn't laser it off the way Intel does; but don't really care); is that ECC RAM can (and should) report even correctable errors; so you get considerably more warning than you do with non-ECC RAM.
If you pay no attention to error reports ECC or non-ECC are both rolling the dice; though ECC has better odds; but 'proper' ECC and Linux-EDAC support will allow you to keep an eye on worrisome events(normally with something like rasdaemon, not sure what other options and preferences there are in terms of aggregating the kernel-provided data) and, unless the RAM fails particularly dramatically and thoroughly, will give you much better odds of knowing that you have a hardware problem while that problem is still at correctable levels; so you can take appropriate action(either replacement, or on the really fancy server systems, some 'chipkill'-like arrangement where the specific piece of DRAM that is failing gets cut out of use when deeemed unreliable without having to bring the system down.
