What brokerage is the best for Algorithmic trading?

I have developed one already for non-us market and trade using that.

I intend to develop another trading bot for US marlets to automate my trades based on technical analysis.

I have a few brokers on my mind for using their APIs on stocks and options.

tdameritrade
Interactive Brokers

Which one do you use?

I looked at r/algotrading already.
