For me, I would have to say Uncharted. By the time I go to crushing, I pretty much knew were everything was and what to expect so it wasn't so tough.
R2 wouldn't be so bad if it wasn't for the 10K Kill Trophy. One thing you can do to help you get platinum is when you beat it on hard, don't play through the whole game on Superhuman. Instead just play the last whole level (all of New Mexico). You should have the OMGWTFBBQ trophy in less then an hour.
Burnout wasn't too bad and wasn't too bad of a time sink either.
