IBKR wins decisively on margin rates and international access — if you borrow to invest or trade globally, there is no contest. Schwab wins for simplicity, branch access, and the thinkorswim active trading platform. Both are excellent brokers. Choose IBKR if you trade actively or use margin; choose Schwab if you want a one-stop shop with human support.
