I actually almost said this in my original post. Pandora could definitely use a third attraction, but even with that it still feels more complete than the others. It's really a hierarchy where Pandora > SWGE >>>> TSL, though, since I think TSL is maybe the worst area Disney has ever built. SWGE and Pandora both dwarf it in terms of things to see/do.
Pandora is just lucky in that visuals of the land itself is part of the draw. It's why I've said from the start that SWGE should have been a more visually distinctive location. I also think that the two Pandora attractions are better overall than the two in SWGE. I haven't been on Rise yet, but I think I'll like it more than FoP -- but I also think NRJ is vastly superior to Smugglers Run. Again, TSL isn't even in the running here unless you count TSMM, but I actually think TSMM is one of the worst rides at Disney so that doesn't help it for me (I know that's a minority opinion).
