Blood Omen on PC's not too bad as long as you know what you're doing during the setup process, better load times but I'm sure emulation would be fine as-well.
Soul Reaver's PC port fucking sucks. Controls are fucked, music's fucked, graphics are the same as on PSX except for the resolution (framerate's locked at 30 unless you use a mod). Emulate the Dreamcast or PSX version instead.
Soul Reaver 2 runs fine on PC from my experience.
Blood Omen 2 runs fine too, though it's more prone to crashing and compatibility issues. Emulating the PS2 or Gamecube (and this is strangely the only LoK game that came out on a Nintendo console) version might be a better idea.
Defiance runs okay on PC from what I recall.
So to recap:
>BO1
Either way
>SR1
Emulate
>SR2
PC version
>BO2
Either way, emulation might be better
>Defiance
PC version
