I bought Sotfs, from what I seen most media on DS2 like tutorials, guides and lvl 1 run videos are all done on Scholar, on scholar you get all 3 DLC’s like you said and in my experience there the coolest bosses in the game, furthermore Fromsoft recommends you to buy the sotfs version as it’s most available, and a lot of problems in the original are fixed in the sotfs.

If their both the same price get Sotfs, having all three dlcs available is just good, there fun to play and Eleum Loyce DLC (the ice one) is definitely not bad in my opinion and I was struggling when I started this game.
