SotC has problems (pacing, emptiness of the field) but the core boss fights still hold up completely. ICO, on the other hand, has been completely superseded by every platforming game that followed improving on its mechanics, combat, and level design. yes the castle was amazing in 2001 but it's 2011 now and Fumito Ueda didn't invent "A and B actually connect," just parlayed it into a 3 2 game career.
