skyrim se is by far superior.i run luminos ENB and i ts awsome geting 60 Fps no problem even with my 10 year old cpu ,including all the mods that i run in oldim made for se .With oldrim i barely get 12 in exteriors .YES some mods use SKSE like frostfall big problem with in oldrim . yet i like it more in skyrim se, no skse .Mods in oldrim has become way to complicated and thats whats robbing it from FPS.in fact i think i have more mods in SE except some mods that you get from some"other" sites .i really only want skse to run HDT physics .im sure some one could make a simple skse version for that we dont need the other complicated mods .IF skse64 will ever co online then we will see the same problem with SE but it would look alot better and the FPS would not drop so much Less is More
