I'm not trying to win, child. I'm just done.
Factor in shipping and the time your waiting, I'd still say PSN is better. And that isn't new.. Digital won't ever break (unless your console does) and I've never came across a bug that wasn't on the disc to begin with.
Hm Can you redownload things of PSN if your console does break? I've never tried, though when I used to have a 360 I think you could as long as it was the same account.
Only children resort to name calling over what should be a courteous debate

You say you aren't trying to win but indirectly claim a victory on the pretense I refuse to listen to (your) reason but yet you refuse to argue the individual refutations I make against your original counter to my argument.
As for wait time, sure it takes a few days to get the physical copy but I am pretty sure (I may be wrong though) if you own a physical copy, you are legally allowed to download a digital copy as a backup (at the very least, they aren't going to waste their time on you). So if you don't want to wait for your copy to arrive, you can always download it while you wait. Even if it is technically illegal, I'm pretty sure you are morally fine.
If your PS3 breaks, you are screwed for playing your port. If you own an original copy or pirated copy on the original system, you can still play it on any number of other platforms.
Again, how is buying a port on PSN better than having a copy on the original platform?
As far as redownloading is concerned, I would imagine you can redownload provided you use the same account.
