My general guidelines:
If I'm recording 24 bit, I just record with a limiter to prevent clipping. I still try and set it so that limiter never, ever activates. The limiter is only there for the rare occasion that a freak spike might ruin a great take.
If I was to record 16 bit (and I really don't anymore), I might record with a compressor only if the vocal part was really dynamic.
The bottom line is that I prefer to record dry. Keep in mind a huge reason for this is that I have pretty mediocre compressors.
