Unfortunately, there is no "best" system. Both the technologies you ask about are commodities. Consider looking at what is available and determine how best the appliance interfaces with you.
For the brake system connect/disconnect tasks, what must you do to properly connect/disconnect the appliance? If portable, where do you store it? How does the unit interface with the driver? Is the interface easy to understand, when driving?
As for the TPMS, the questions are the same. Is there anything one must do to start or stop the system? Is the interface to the driver easy to understand, when driving? Lights and bells can get confusing very quickly.
For the last 6+ years, I have used USGEAR for a supplemental brake system and a Pressure Pro system for the TPMS. Both work as advertised and I would make the same purchases again.
