I'm finding this difficult to answer.
Ray tracing should, in theory, make for much better visuals. But I haven't actually seen many examples where it makes things look incredibly better without tanking performance.
Frame gen I'm not enamored with at all. It works best when your frame rate is acceptable anyway, when you need it and your frame rate is low it makes the game feel a lot worse so you're better off lowering the settings anyway.
Upscaling I find better than frame gen but I'd still rather run at native resolution. It seems like you need the latest and greatest GPUs to take advantage of the best upscaling options and, in my opinion, the latest and greatest GPUs shouldn't need to be upscaling stuff!
If I had to make a choice I'd say that ray tracing would be the only positive tech there. The others are just ways of disguising hardware that isn't up to the job. Ray tracing at least has the potential to make things look better if it's implemented well, the other two make a game experience worse imho.
