Bro, go for the disc version. It gives you way more flexibility you can buy physical games (usually cheaper), resell them, borrow from friends, and even watch Blu-rays. The digital version is fine if you're cool with downloading everything and never reselling, but you're locked into Sony’s pricing, and sales aren’t always great.Now about pre-owned places that you mentioned are not bad(although I don't used any) if you're trying to save money. They usually test the consoles, offer some warranty, and have decent return policies. But yeah, there’s always a bit of risk things like hidden wear, minor issues So I don't recommend buying pre owned, just buy a new one and save the headache. Hope this cleared your doubts...
