Well, sneaking in Dreamfal was neither very bad nor very good. It just looked as some necessity (not very tough, though) to move further.
If you play in Thief (or Hitman, Splinter Cell) and hide from guards and zombies (especially zombies - one scream of them can turn you white), sneaking in DF won't be super challenging.
It would be better, if developers have replaced sneaking parts with some interesting puzzles (like in TLJ - there were many parts in it with puzzles instead of possible sneaking). Or added some way (trusty blackjack) to neutralize guards and after that explore location in calm atmosphere.
