Slight DPS increase over Fpsware's DK CR, they both survive roughly the same, but as far as fluidity goes, Fpsware's CR runs much smoother to me. They're both excellent CRs, and I know TuanHA's will be for dungeon/raid use in the end, but right now I'm having a hard time deciding which to use, so I alternate.
Questing: Fpsware's Multiplicity
Dungeons: TuanHA's DK
Grinding: Fpwware's Multiplicity
Raiding: TuanHA's DK
PVP: I don't PvP
Farming: Fpsware's Multiplicity
The above are just my opinion, and I am in no way putting one down over the other. They're both done by two excellent coders. Fpsware is known for his leveling CRs and TuanHA is known for his end-game CRs. This is why I use them both. It all depends on what I'm going to be doing.
Note: When I say that Fpsware's CR runs more fluidly, what I mean is that TuanHA's seems to be sort of jerky and hiccupish. Fpsware's just flows from one thing to another. There are slight pauses with TuanHA's. However, once in dungeons, Fpsware's seems to run slower and it seems to hesitate as it's cycling through its logics. TuanHA's does this also, but not nearly as badly as Fpsware's.
I do know that TuanHA's is still in alpha testing (since he's writing it as he goes along), and it has a long way to go to catch up to his monk and paladin CRs, so I have no doubt that this will, in the end, be one of his ultimate creations to rival his SPriest, Paladin, and Monk CR. This was considered in my opinion, and also contributed towards my opinions.
