IMHO, if feathers is what you are looking for and if it's for jigs, I like Hareline's Feathers more than anyone else so anyone that sells Hareline packs would be very good, but they are higher cost because they use Saltwater Neck Hackle which is a little longer. However there are a ton of different kinds of feathers you could want and if it's for flies then Whiting Farms is as good as it gets as well Conranch Hackle use to have excellent quality, but there is also Metz and a few other that sell good quality feathers. Regular Neck Hackle would be who ever sells WAPSI Feathers like Crazy Angler as well as most fly tying shops. It really doesn't end here either as we have not even talked about soft hackle which can be hen or even Rooster or many other types of birds. This is a huge topic or can be.
