I found Strat much easier and slightly more fun, once I had the rythym down, I was getting far more XP/h and the mobs are simple to kill, plus unlike SM/Scholo I wasn't hitting the instance/h cap which is really annoying.

However I did do both Scholo and Strath to get my T set's

Another cool thing about Strath is the ammount of Pristine black diamonds and rightious orbs that drop, the former sell for 200g on my server, the rightious orbs, not so much, but they easily paid for repairs.
