While McMillan is an excellent stock it is fairly expensive. HS Precision stocks are very good, much better than the factory stick. The B&C stock is a very good value, and really quite a good stock. Houge stocks are inexpensive and popular, but I do not like them.
If you are deciding based upon just weight alone your decision should be easy, but usually other factors (cost, availabiliity, etc.) come into play. I would not shy away from buying the HSP or B&C just based on weight and internet opinions. They are very good stocks. I buy some stocks from Stocky's Stocks. I like Stocky's, but find that I can buy them for less and get more options by buying directly from the manufacturer.
