Last June Origin had a meltdown with a lot of users unable to download anything. EA was absolutely horrible in addressing this, they never really did. It took me over 20 days to be able to download anything from the site.
And many, many other Simmers and users of other EA games had this issue as it came during an Origin sale.
Other people who did manage to get some kind of response from Origin help were given bad information and wound up worse than if they did nothing.
Bottom line, I will not now, nor not anytime soon ever recommending buying a download from Origin. Pay a $10 more and get the disk.
To be fair, Steam also had it's fair share of issues but being older has worked out most of the glitches, but to be more fair, Steam is much better at addressing issues with the Steam client, even if it's just to say "OK we don't know, hang on it might be a week." At least they don't hang you in thin air with no response.
