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
One of the most powerful low-cost platforms for active equity and options traders in the US. Free NASDAQ TotalView Level 2, $0 equity options, flat 6.8% margin, and Hong Kong/China A-share access. Structurally incomplete: no IRAs, no joint accounts, no mutual funds, no bonds.
Each broker scored 0–5 across the same 8 dimensions.
