Buying Hickey Freeman and H. Freeman and Sons Suits

I have often seen men's suits for sale on okay that are listed as Hickey Freeman. Often times, these suits are actually H. Freeman and Sons. What's the difference? A lot, and not a lot. They are both high quality American made suits. Hickey makes their suits in Rochester, NY. H. Freeman has a factory in Philadelphia. Both use high quality fabrics and sew much of the garments by hand. Both manufacturers make traditional American style suits. They are both old line traditional suit manufacturers. Both are sold in higher end men's stores and department stores.
