Martha was a good companion but wasn't the best by far! I much preferred her when she popped up in Torchwood. Companions are usually really hit and miss. I think Amy had such potential but they ruined her by making her The Doctor's mother in law or whatever the pointless River storyline was. (I do adore River though.)

Clara is one of my favourites, post-series 7 that is. The impossible girl stuff wasn't great, but she came into her own in Series 8/9 and was bloody fantastic. I think she carried the series.
