Head-to-head comparison across ratings, fees, asset coverage, and platform breadth.
Charles Schwab (thinkorswim)
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.

Firstrade
4.0 / 5
Best for OTC and penny-stock buyers who want $0 commissions, plus mainstream mutual-fund and 24/5 access. Smaller platform and research footprint than the big four, but the price floor is uncontested.
