I use M1 for my long term savings.
It’s free to use and makes investing easy.
I like Ally for my car and home sinking funds.
I like Fidelity for trading and only have TD Ameritrade for stock options since I took a TSP loan for the home purchase and wanted to hedge being out of the stock market. I am in about 90% stocks
We each have an IRA at Fidelity, and have post-tax brokerage accounts with Fidelity and Schwab.
I have one ira with m1 and one with J.P. Morgan.
If you have Bank of America. They give some very good benefits for having a high value ira with them.
