Which is the best brokerage firm in USA?

Question

for individuals....

Answer 1

for individual or corporation? anyway, "best" is subjective

Answer 2

There is no "best" brokerage firm in the US

All major brokerage firms provide their clients with on-line and in house services, including trading platforms, latest market, financial news, research, corporate finance, money markets and a full array of account types so they can access any US market and invest in any type of security product .

Customer need to select the firm that is best for them.  Traders have requirements from a firm, while investors have other requirements. Most major firms try to satisfy all types of customers, both foreign and domestic

Although most firms are geared to general securities and commodities, however customers may have special needs for the types of products they trade, and the markets in which they trade.  

You can read in Barron's who provides ratings of firms,. but the sampling is not that accurate along with their findings.

So to answer you question, there is no "best" firm and any one that tell you differently their opinion is not based on reality only personal preference.
