Duncan is truly great in my book. My Antiquity I bridge pickup is my all-time favorite pup. You can't go wrong with Seymour, IMO. What type of music do you play ? What type of tone are you attracted to ? What players ?
In my experience, Klein is amazing and OC Duff great, others swear by Don Mare. My advice is: go to their websites and read the descriptions. Audio clips don't do pickups justice. My Klein Broadcaster bridge is sooo much better than the clips on the website, however good sounding they were. You just never know until you install them in your guitar and play through your amp. JMHO YMMV
