On Metzers website buffs are alittle bigger, lay more eggs and are more fertile. Truly I think if you like the look of buffs better go with them. If you prefer the look of pilgrims, go with them. The main difference is color and that pilgrims are auto-sexing. It came down to buffs and pilgrims for me as well. I ended up with buffs because the color was different from white or grey. Good luck!
