Yet another Dr. Who Question...?

Okay, here in the States on PBS we are just on Series 1, I think, with C. Eggleston (sp) and Billie Piper.... I LOVE these two... Okay So I know we get a new Doctor (i've seen that ep) and something happens to Rose (Don't want to know) What I WANT to know, is the chemistry between the new Doctor and Martha as great as between the Doctor and Rose?
