I haven't tried the 57/08, but I've just swapped a 59/09 out of the neck position in my DGT. Personally, I was disappointed with the 59/09 as it performed in my guitar. In my DGT at least, it sounded a bit nasal, thin and had a very early treble cut off (like the tone control was wound back). It did however find it very good split - quite single coil like (so much so I sold my Tele). Others find them brilliant - so I guess it's all down to taste and how the pickup performs in a particular guitar and rig. However, given the price differential, I would have thought the BKP route would be a no-brainer.
