Best Exceution/Routing Choice for Breadth of energy products?

Since Interactive Brokers does not offer some energy products that I want (such as implied contracts and Brent options), I am looking at others.

Which of the following execution and routing choices would offer the widest range of energy products worldwide, including spreads and options:

-Rithmic
-CQG
-Trading Technologies

(I am not asking about the user software platform as such, which can be a separate issue because you can mix and match to some extent at brokers like deepdiscounttrading, a Crossland IB. I will place orders manually for now that are position trades so I do care about the UI or about charts or static DOM and will just choose a low-end software platform to start with.)

If the breadth of the range of products depends also on the broker, as well as on the execution and routing choice, I am also open to using any broker.

Thanks for any comments.
