For what it's worth, I've had a fairly good experience with HSRminer, particularly with Just_a_miner's fork. I like to restart it once every 8 hours or so and it'll often produce the hash rates I see on client-side.

I've heard good things about KlausT if you're willing to mess with intensity, but I haven't tried that myself. Stock KlausT is underwhelming IME. NH's Excavator (1.4.4 I believe?) is also excellent for Neo when it comes to 1080Tis/TitanXPs. Not sure what their licensing details are, but might be worth replacing HSRminer if it's (relatively) easy to integrate.
