parallel
it's up to you, but the question was what would [ I ] go for, and I would go for it for many reasons:
- No 60-cycle hum. (Like standard single coils)
- Richer tone.
- When distorted, less mud comes out of your amp/speaker.
- More unique, not that common.
- It can give you a single-coil - like vibe but doesn't get very thin as a coil tap can get. (depending on the humbucker)
