It is up there, that is for sure. The combat is so satisfying though, I will say nothing beats it in that regard.
For me it tues with...
Breath of the Wild
Xenoblade 2
Bloodborne
Witcher 3
Uncharted 4 is up there as well, but I rank that just beneath GoW and the games listed above. The important take though is that all of thise games are of different play styles, and excel in their own way. The title of "best game this gen" is subjective to a number of factors, and while it fits the bill overall for those seeking this type of gameplay, there are others that do as well for their own playstyles.
