To make Demo work well, you really need the Unerring Vision of Lei Shen trinket. If you have it, then by all means go Demo, but it is imo the hardest spec of the 3 to play well and has the least margin for error (especially with the trinket, as the proc window is quite small so you need to be able to react to it quickly).
Destro atm works at any gear level, and is perfectly competitive and indeed the highest lock DPS spec on certain fights that have multiple adds (Horridon HC is a good example). It is also not the most difficult of specs, so you can do well without having to play to the best ability.
