I've encountered minor hiccups with the latest build (occasionally about 50% of displayed text will start flickering) but previous load/save crashes seem to have been fixed and savegame times have been greatly improved (loading still takes longer than it should IMHO at 15-20 seconds). In terms of stability, I'd rate this as good though it would (and likely will) benefit from further improvement.
That leaves the question of whether you would enjoy D:OS as a game, which is much more subjective. If you like complex RPGs with freedom of action, this is likely the best candidate around (until Pillars of Eternity, Wasteland 2 or Age of Decadence get finished) since you can interact with so many objects in the game world and the quests often have several ways to resolve them.
It is quite light-hearted in some places (like the conversations with animals you can have with the Pet Pal skill) which may not be to everyone's taste and some have issues with the combat system, crafting or general game balance.
The biggest downside I'd say is the UI with inventory management in particular being less streamlined than it could be.
