So even if SS increased DoT dmg more than crit + det, you still get more dmg increase to other places along side the lesser increase to DoT ticks. So from that perspective I'd say crit + det beats SS on any class (excluding "soft cap" for SS to get 1 extra GCD out during certain skills for example Warrior + berserk)
If mch had say 3-4 DoT skills, it could possibly be different case. But with only 1 I don't belive SS being better choise considering dmg output
