The difference is that it can be fun to role-play a weak warrior, a stupid mage or a clumsy thief - or disagreeable bard. No computer game come close to that kind of storytelling / social / intelligent interaction though. The second best thing is stuff like Moria/Angband where each stat has a clear use and game effect - and of course in such games some form of re-roll/prioritization makes a lot of sense (the automagic re-roll based on min-stats targets (I need at least 17 dexterity) introduced in some version of Angband is probably the best if you want player-visible stats).
