Rubinstein French

The Rubinstein French is a good defense, but it requires refined defensive technique. I was advised by a master level player that I should avoid it because it gave few winning chances and would ruin my chess. The best White response is the system with Qe2 and development on the light squares such as 1 e4 e6 2 d4 d5 3 Nc3 dxe4 4 Nxe4 Nd7 5 Nf3 Ngf6 6 Bd3 c5 7 Qe2.
I know the RF has been considered boring, but is it a good defense? white is the best white response?
