Not really sure about quick fills or what it does for you. But I like larger spreads like square because if you hit it the right direction you could be up a good chunk and the spread is usually 5 to 10 either way. If your trying to make money wouldnt you want larger spreads. Larger spreads = more money when it's going your way.

He is talking about the spreads in the bid and ask prices. Not the movement in stock price.
