Who is the best companion in Doctor Who?

Sarah Jane Smith needs to be on here.

Donna is my favourite. I didn't like her at first, but she Had good acting chemistry with Tennant.

no idea haven't watched it in over 20 years

How about Donna Noble?

Come along ponds!

David tennant and billie pipper and matt Smith and Amy ONF

I think Martha was probably the most competent outta those people, but I like Rory the most
