If your system exceeds the minimum requirements, go for the PC version; if it doesn't, go for the PS4 version. Should the former happen to be terrible for one reason or another, at least on Steam you'll have a two-week window post-release within which to claim a refund (provided you don't play more than two hours).
Thing is, the game is about 200SEK cheaper retail (here in Sweden at least) for PC than buying it on straight Steam

PC Digital prices for big games really are shit on Steam compared to retail.
