Head-to-head comparison across ratings, fees, asset coverage, and platform breadth.
4.5 / 5
Best for full-service investors who want thinkorswim, broad 24/5 trading, deep customer service, and integrated banking. Cost-competitive on most fronts but lags on margin rates and fractional-share breadth.
4.2 / 5
Best for systematic and futures traders who want EasyLanguage scripting, direct routing, deep back-testing, and active-trader margin rates. Less retail-friendly than thinkorswim but unmatched for strategy automation.
