I think Guardians is usually considered a pumped up Space Mountain. It's a cool attraction but it still largely Space Mountain with added music and having been on it during Previews where it stopped halfway through yeah it's Space Mountain there. My husband does love it though and it's his fav ride at Disney presently speaking.
Tron I think has some wow factors to it but many complain about the shortness to it (I haven't been able to ride it yet). And the lights/ambience at night is awesome at least from the pics.
That said FOP was/is really really cool but in some ways is like a pumped up Soarin'. It does have innovativeness to it with how the ride vehicle with the 3D aspect to it is quite immersive, sitting the way you do combined with how it works makes you
feel story.
Doesn't mean Disney hasn't been using creative aspects to their rides but I def. see built upon similarities to their attractions. I'm still very glad they did Pandora and it's one of my fav areas (plus Satu'li Canteen is really good QS) at any Disney park and I know my husband really loves Guardians (though I still miss Ellen

).
