Definitive version is the last-gen SotFS bundle. That release integrates the DLC, but also has the same layout as the base game (i.e. the other SotFS changes aren't present).
I wasn't a big fan of the changes they made in SotFS. Some parts were better, but many other parts took an inexplicable step back.
As for the game as a whole, it's got the most content in the series (by far I'd say). Some of that content is excellent, some of it is abysmal. Just because people can point to truly dumpster fire-tier content doesn't mean the game is bad, it's just fairly uneven. The DLC, for instance, is A+ Souls content, the three of them combined are possibly my favorite levels in the series.
EDIT: It's a major bummer that you don't get a choice of whether or not to play the original layout or the SotFS updated version.
