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.
4.0 / 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.
