There is no difference.
Only difference is if it has a ticket that wok on OFW. legit bought stuff has a ticket that works on your console with OFW.
ciangel and freshop (with that site's data) will give you a ticket that only work on CFW.
once you have a ticket, whether it's cfw or not, you get the same files. Eshop itself doesn't validate the ticket, the firmware does that. SO a long as it's not DLC and you have a ticket, the official shop lets you redownload. Eshop will erase all non legit DLC when you go in.
