I think Sarah Jane said it most plainly in School Reunion: "You know what the most difficult thing was? Coping with what happens next, and with what doesn't happen next. You took me to the furthest reaches of the galaxy, you showed me supernovas, intergalactic battles and then you just dropped me back on Earth. How could anything compare to that? [...W]e get a taste of that splendour... and then we have to go back."
I guess the reason it doesn't bug me (or at least not very much) in DW is that the companions still love the Earth. Most of them still have ties there, and they care what happens to the other people there. They'd rather be adventuring with the Doctor, but it's not like they can't find anything good to live for on Earth.
In Neverwhere I can't remember Richard Mayhew regretting the lost of anything at all from his life on Earth. Once he realized how shallow his fiancee was, he had no ties, no concerns about anyone back at home.
