Unfortunately I do not have enough specific information about all of those brokers to provide a detailed feature comparison. Some high-level differences that may be relevant when evaluating brokers include:

• Account minimums and fees - Some brokers have higher minimum deposits to open accounts or charge more fees for trades and services. Robinhood and eToro tend to have lower or no minimums. Merrill Edge and Wealthfront also do not have account minimums.

• Trade platforms and tools - Brokers offer varying degrees of sophistication in their web/mobile platforms and availability of screening tools, research, charting etc. Thinkorswim from TD Ameritrade is well known for its platform. Interactive Brokers also has an extensive platform.

• Investment choices - The range of available investments differs significantly. Most offer stocks, ETFs, options and mutual funds. Interactive Brokers offers foreign ordinary shares. Some include cryptocurrencies or fractional share investing.

• Customer support - Review response times and support channels like phone, chat, branches. Many of the more traditional brokers like Fidelity and Merrill Edge have physical branches and large support staffs.

• Account types - Availability retirement accounts like IRAs as well as account types for trusts, joint accounts, custodial accounts etc. can vary.

Without more specific requirements on features, it is difficult to compare all aspects feature-by-feature across such a large group of brokers in a single table. Let me know if you need details on evaluating any specific brokers or account types based on your needs.

Here is a table comparing some of the important features of the brokers you mentioned:

Please note that this is just a summary of some of the main features of these brokers, and there may be additional features or differences depending on your specific needs and circumstances.
