Head-to-head comparison across ratings, fees, asset coverage, and platform breadth.
4.6 / 5
Best for active, global, and advanced traders. Lowest margin rates in the industry, broadest international access (160+ exchanges, 36 countries), and the most complete API stack in retail brokerage.
4.0 / 5
Best one-app financial life for beginners and casual investors. Unbeatable on $0 options + IPO access + 1% IRA match. Avoid if you trade OTC, options spreads professionally, or hold meaningful idle cash.
