I went with Amazon, too ... I've had pretty good luck with the big boxes. The smaller box special editions they'll sometimes force into a bag, though. Considering the digital is $49.99, it was a no brainer to get the limited edition with the Prime discount.
Two friends and I got the game last night, the only single player I tried was the tutorial where the game ran well on my PS4 Pro.
When we went online it was a bit of a nightmare. I don't know if it was the netcode or because we're in Australia and the game isn't even out on PSN here yet, but it was borderline unplayable. It didn't help that there was only a handful of other players online who had leveled themselves and their weapons up considerably.
It was much better and smoother when we played co-op survival and that was awesome.
Keen to delve deeper into the game it seems like there's lots to upgrade and tonnes of skill cards to collect.
