Glen's Verdict

IBKR wins for active traders, margin users, and anyone trading internationally. Fidelity wins for simplicity, customer service, and buy-and-hold investors. The honest answer: open both — Fidelity for your retirement accounts and long-term holdings, IBKR for active trading and margin. IBKR's margin rates alone can save serious traders thousands per year.
