seeing as i play wii u and computer, it really depends. i personally prefer digital on PC, but on console, physical is really the only thing you can do. there are some really good physical games on PC< but it is mostly digital games, like terraria.
Digital for me. Easy to replace, in case something goes wrong, quick to be actually downloaded and installed, all the latest patches etc. etc. Besides, here the retail stores don't usually have a lot of games, only the latest and all are priced at 60 Euros obviously. With digital stores, you can look through tempting offers
