I guess you and I have different opinions on what makes a "better" broker. I'm in favor of clearly-defined policies that anticipate certain events, which are communicated to all customers far in advance, so customers can make an informed decision whether or not to patronize that particular company. You seem to be happy with firms like IBKR which might decide, mid-day, at the peak of volatility, to lock out its customers from trading certain securities, without any advance notice or warning.
