Eh, UI matters to, and be able to put orders down on spreads is really nice too (especially when you can't afford to buy each leg as a single). I don't regret moving on to TW at all.

Robinhood allows spreads as a heads up all in one trade and commission free. You save an assload on commissions if you trade spreads, iron condors, and butterflies with multiple legs.
