I have accounts with Fidelity, Vanguard, and USAA (USAA is for military members or their spouses/children, so may not be available for you).
I am pretty much mutual-funds only and don't do much stock trading so I cannot comment on the day-trading aspect of your question. I actually like all of them (Vanguard and Fidelity for the ease of use and information available online, USAA for the customer service), but if you were to ask me to pick just one I would lean toward Vanguard. Since I don't see that mentioned in your post maybe check them out? Happy investing!
